+# Smart Doc Generator (Dify Plugin)
+
+A smart Markdown to Word document generator with **automatic chart generation** (pie charts, bar charts, line charts) and flexible template mechanism, enabling rapid generation of formatted Word documents with rich visualizations for various scenarios.
+
+## Overview
+
+Smart Doc Generator is a powerful Dify plugin that converts Markdown content into professionally formatted Word documents (.docx). **The plugin's standout feature is its intelligent chart generation system** that automatically recognizes data patterns in Markdown and generates beautiful, professional charts (pie charts, bar charts, line charts) directly embedded in Word documents. Combined with a flexible template system, it enables rapid generation of data-rich, visually appealing documents.
+

+
+## Chart Generation Guide
+
+### How Chart Generation Works
+
+The chart generation feature allows you to automatically insert professional charts into your Word documents. Here's how it works:
+
+1. **Enable Chart Generation**: Set `enable_charts: true` in your tool parameters
+2. **Provide Chart Data**: Pass chart data in JSON format via the `chart_data` parameter
+3. **Specify Chart Position**: Define where charts should appear in the document using the `position` field
+4. **Automatic Rendering**: The plugin generates the chart image and inserts it into the Word document
+
+### Chart Data Format
+
+The `chart_data` parameter accepts a JSON object with the following structure:
+
+```json
+{
+  "charts": [
+    {
+      "type": "pie" | "bar" | "line",
+      "title": "Chart Title",
+      "position": "after:Heading Text" | "before:Heading Text" | "after:Table Title",
+      "data": {
+        "Label1": value1,
+        "Label2": value2,
+        ...
+      }
+    }
+  ]
+}
+```
+
+### Chart Types
+
+#### Pie Charts
+Perfect for showing proportions and percentages:
+```json
+{
+  "type": "pie",
+  "title": "Market Share",
+  "position": "after:Market Analysis",
+  "data": {
+    "Product A": 35,
+    "Product B": 25,
+    "Product C": 40
+  }
+}
+```
+
+#### Bar Charts
+Ideal for comparing values across categories:
+```json
+{
+  "type": "bar",
+  "title": "Monthly Sales",
+  "position": "after:Sales Data",
+  "data": {
+    "Jan": 1000,
+    "Feb": 1500,
+    "Mar": 1200
+  }
+}
+```
+
+#### Line Charts
+Great for showing trends over time:
+```json
+{
+  "type": "line",
+  "title": "Revenue Trend",
+  "position": "after:Financial Overview",
+  "data": {
+    "Q1": 50000,
+    "Q2": 55000,
+    "Q3": 60000,
+    "Q4": 65000
+  }
+}
+```
+
+### Chart Positioning
+
+Charts can be positioned relative to document elements:
+- `"after:Heading Text"` - Inserts chart after the first occurrence of the specified heading
+- `"before:Heading Text"` - Inserts chart before the specified heading
+- `"after:Table Title"` - Inserts chart after a table with the specified title
+

+## Template Configuration
+
+### Theme Configuration File
+
+Theme configuration is located in `src/templates/themes/theme_config.yaml`:
+
+```yaml
+themes:
+  default:
+    name: "Default Theme"
+    description: "Formal theme suitable for system alerts and monitoring reports"
+    style_template: "default.yaml"  # Referenced style template
+    color_scheme:
+      primary: "#d32f2f"      # Primary color
+      secondary: "#ff9800"    # Secondary color
+      accent: "#2196f3"       # Accent color
+      background: "#ffffff"   # Background color

+      table:
+        header_background: "#f44336"
+        header_font_color: "#ffffff"
+```
+
+### Style Template Files
+
+Style templates are located in the `src/templates/styles/` directory:
+
+```yaml
+# Page settings
+page:
+  width: 21.0      # cm
+  height: 29.7     # cm

+  font_family: "Consolas"
+  font_size: 9
+```
+
+## Custom Templates
+
+### Creating a New Theme
+
+1. **Edit Theme Configuration**: Add a new theme in `src/templates/themes/theme_config.yaml`:
+
+```yaml
+themes:
+  my_custom_theme:
+    name: "My Custom Theme"
+    description: "Theme suitable for my business scenario"
+    style_template: "default.yaml"  # Can reuse existing style template
+    color_scheme:
+      primary: "#0066cc"
+      secondary: "#666666"
+      # ...
+    overrides:
+      fonts:
+        body:
+          name: "Microsoft YaHei"
+          size: 12
+      # Other override settings...
+```
+
+2. **Create New Style Template** (optional): If you need a completely new style configuration, create a new YAML file in the `src/templates/styles/` directory
+
+3. **Use New Theme**: Specify the theme name when calling the tool:
+
+```yaml
+templates: "my_custom_theme"
+```
+
+## Troubleshooting
+
+- If Dify results show an empty `files` array, ensure your environment uses a plugin version that supports file BLOB returns (this project already supports it)
+- Very large Markdown inputs may require longer conversion times
+- When customizing themes, ensure YAML format is correct to avoid syntax errors
+- Font names must be installed on the system, otherwise default fonts will be used
+- Color values in style templates use hexadecimal format (e.g., `#d32f2f`)
+
+## Template System Advantages
+
+1. **Flexibility**: Through theme and style template separation, achieve highly flexible style customization
+2. **Maintainability**: Centralized style configuration management, easy to maintain and update
+3. **Extensibility**: Easily add new themes and style templates without modifying core code
+4. **Consistency**: Ensure document style consistency through templates
+5. **Usability**: Predefined themes ready to use, lowering the barrier to entry

+# Privacy Policy
+
+## Overview
+
+Smart Doc Generator (the "Plugin") is a Dify plugin that converts Markdown content to Word documents. This privacy policy explains how the Plugin handles user data and information.
+
+## Data Collection
+
+**The Plugin does NOT collect, store, or transmit any user data.**
+
+### What We Don't Collect
+
+- Personal information
+- Markdown content or document data
+- User credentials or authentication information
+- Usage statistics or analytics
+- IP addresses or device information
+- Any other user-generated content
+
+### Local Processing Only
+
+All data processing occurs **locally** on the Dify instance where the Plugin is installed:
+
+- Markdown content is processed entirely within your Dify environment
+- Generated Word documents are created locally
+- No data is sent to external servers or third-party services
+- No network requests are made for data processing
+- All operations are performed on-premises or within your cloud infrastructure
+
+## Data Processing
+
+### What Happens to Your Data
+
+1. **Input Processing**: When you provide Markdown text to the Plugin:
+   - The content is processed locally within the Dify plugin runtime
+   - No copy of the content is stored permanently
+   - Processing is done in memory and temporary files (if needed)
+
+2. **Document Generation**: During Word document generation:
+   - Charts and images are generated locally using matplotlib and other libraries
+   - All processing happens within the plugin's execution environment
+   - Generated files are returned directly to the Dify workflow
+
+3. **Temporary Files**: 
+   - Any temporary files created during processing are cleaned up automatically
+   - No persistent storage of user content is maintained
+
+### Data Retention
+
+- **No data retention**: The Plugin does not retain any user data after processing
+- **No logging**: User content is not logged or stored in any persistent format
+- **No caching**: Generated documents are not cached or stored by the Plugin
+
+## Third-Party Services
+
+The Plugin does not integrate with any third-party services that would collect or process user data. All dependencies are open-source libraries used for local processing:
+
+- `python-docx`: For Word document generation (local processing)
+- `matplotlib`: For chart generation (local processing)
+- `markdown`: For Markdown parsing (local processing)
+- Other dependencies: All used for local data processing only
+
+## Security
+
+### Data Security
+
+- All processing occurs within your secure Dify environment
+- No data transmission over networks
+- No external API calls for data processing
+- Follows your Dify instance's security policies and configurations
+
+### Best Practices
+
+- Ensure your Dify instance is properly secured
+- Follow your organization's data handling policies
+- The Plugin respects all security configurations of your Dify deployment
+
+## Compliance
+
+This Plugin is designed to comply with data privacy regulations including:
+
+- **GDPR (General Data Protection Regulation)**: No personal data collection or processing
+- **CCPA (California Consumer Privacy Act)**: No data collection or sale
+- **Other privacy regulations**: As no data is collected, the Plugin inherently complies with most privacy requirements
+
+## User Rights
+
+Since the Plugin does not collect or store any user data:
+
+- **Right to Access**: No data is stored, so there is no data to access
+- **Right to Deletion**: No data is stored, so there is no data to delete
+- **Right to Portability**: No data is stored, so there is no data to export
+- **Right to Correction**: No data is stored, so there is no data to correct
+
+All your data remains under your control within your Dify instance.
+

+
+## Chart Generation Guide
+
+### How Chart Generation Works
+
+The chart generation feature allows you to automatically insert professional charts into your Word documents. Here's how it works:
+
+1. **Enable Chart Generation**: Set `enable_charts: true` in your tool parameters
+2. **Provide Chart Data**: Pass chart data in JSON format via the `chart_data` parameter
+3. **Specify Chart Position**: Define where charts should appear in the document using the `position` field
+4. **Automatic Rendering**: The plugin generates the chart image and inserts it into the Word document
+
+### Chart Data Format
+
+The `chart_data` parameter accepts a JSON object with the following structure:
+
+```json
+{
+  "charts": [
+    {
+      "type": "pie" | "bar" | "line",
+      "title": "Chart Title",
+      "position": "after:Heading Text" | "before:Heading Text" | "after:Table Title",
+      "data": {
+        "Label1": value1,
+        "Label2": value2,
+        ...
+      }
+    }
+  ]
+}
+```
+
+### Chart Types
+
+#### Pie Charts
+Perfect for showing proportions and percentages:
+```json
+{
+  "type": "pie",
+  "title": "Market Share",
+  "position": "after:Market Analysis",
+  "data": {
+    "Product A": 35,
+    "Product B": 25,
+    "Product C": 40
+  }
+}
+```
+
+#### Bar Charts
+Ideal for comparing values across categories:
+```json
+{
+  "type": "bar",
+  "title": "Monthly Sales",
+  "position": "after:Sales Data",
+  "data": {
+    "Jan": 1000,
+    "Feb": 1500,
+    "Mar": 1200
+  }
+}
+```
+
+#### Line Charts
+Great for showing trends over time:
+```json
+{
+  "type": "line",
+  "title": "Revenue Trend",
+  "position": "after:Financial Overview",
+  "data": {
+    "Q1": 50000,
+    "Q2": 55000,
+    "Q3": 60000,
+    "Q4": 65000
+  }
+}
+```
+
+### Chart Positioning
+
+Charts can be positioned relative to document elements:
+- `"after:Heading Text"` - Inserts chart after the first occurrence of the specified heading
+- `"before:Heading Text"` - Inserts chart before the specified heading
+- `"after:Table Title"` - Inserts chart after a table with the specified title
+

+
+## Template Configuration
+
+### Theme Configuration File
+
+Theme configuration is located in `src/templates/themes/theme_config.yaml`:
+
+```yaml
+themes:
+  default:
+    name: "Default Theme"
+    description: "Formal theme suitable for system alerts and monitoring reports"
+    style_template: "default.yaml"  # Referenced style template
+    color_scheme:
+      primary: "#d32f2f"      # Primary color
+      secondary: "#ff9800"    # Secondary color
+      accent: "#2196f3"       # Accent color
+      background: "#ffffff"   # Background color
+      text: "#333333"         # Text color
+      border: "#424242"       # Border color
+    
+    # Custom style overrides
+    overrides:
+      fonts:
+        body:
+          name: "Microsoft YaHei"
+          size: 11
+      headings:
+        h1:
+          color: "#1a1a1a"
+          border_color: "#d32f2f"
+      table:
+        header_background: "#f44336"
+        header_font_color: "#ffffff"
+```
+
+### Style Template Files
+
+Style templates are located in the `src/templates/styles/` directory:
+
+```yaml
+# Page settings
+page:
+  width: 21.0      # cm
+  height: 29.7     # cm
+  margin_top: 2.5  # cm
+  margin_bottom: 2.5

+code_block:
+  background_color: "#f5f5f5"
+  border_color: "#d32f2f"
+  font_family: "Consolas"
+  font_size: 9
+```
+
+## Custom Templates
+
+### Creating a New Theme
+
+1. **Edit Theme Configuration**: Add a new theme in `src/templates/themes/theme_config.yaml`:
+
+```yaml
+themes:
+  my_custom_theme:
+    name: "My Custom Theme"
+    description: "Theme suitable for my business scenario"
+    style_template: "default.yaml"  # Can reuse existing style template
+    color_scheme:
+      primary: "#0066cc"
+      secondary: "#666666"
+      # ...
+    overrides:
+      fonts:
+        body:
+          name: "Microsoft YaHei"
+          size: 12
+      # Other override settings...
+```
+
+2. **Create New Style Template** (optional): If you need a completely new style configuration, create a new YAML file in the `src/templates/styles/` directory
+
+3. **Use New Theme**: Specify the theme name when calling the tool:
+
+```yaml
+templates: "my_custom_theme"
+```
+
+## Troubleshooting
+
+- If Dify results show an empty `files` array, ensure your environment uses a plugin version that supports file BLOB returns (this project already supports it)
+- Very large Markdown inputs may require longer conversion times
+- When customizing themes, ensure YAML format is correct to avoid syntax errors
+- Font names must be installed on the system, otherwise default fonts will be used
+- Color values in style templates use hexadecimal format (e.g., `#d32f2f`)
+
+## Template System Advantages
+
+1. **Flexibility**: Through theme and style template separation, achieve highly flexible style customization
+2. **Maintainability**: Centralized style configuration management, easy to maintain and update
+3. **Extensibility**: Easily add new themes and style templates without modifying core code
+4. **Consistency**: Ensure document style consistency through templates
+5. **Usability**: Predefined themes ready to use, lowering the barrier to entry
