 **Measures to support accessibility**
 Elastic takes the following measures to ensure accessibility of Kibana:
 
 * Maintains and incorporates an [accessible component library](https://elastic.github.io/eui/).
 * Provides continual accessibility training for our staff.
 * Employs a third-party audit.
 
-
 **Conformance status**
 Kibana aims to meet [WCAG 2.1 level AA](https://www.w3.org/WAI/WCAG21/quickref/?currentsidebar=%23col_customize&levels=aaa&technologies=server%2Csmil%2Cflash%2Csl) compliance. Currently, we can only claim to partially conform, meaning we do not fully meet all of the success criteria. However, we do try to take a broader view of accessibility, and go above and beyond the legal and regulatory standards to provide a good experience for all of our users.

 **Feedback**
 We welcome your feedback on the accessibility of Kibana. Please let us know if you encounter accessibility barriers on Kibana by either emailing us at `[email protected]` or opening [an issue on GitHub](https://github.com/elastic/kibana/issues/new?labels=Project%3AAccessibility&template=Accessibility.md&title=%28Accessibility%29).

 ## Querying and filtering
+
 Elasticsearch’s robust query capabilities enable you to retrieve specific data from your datasets. Using the Query DSL (Domain Specific Language), you can build powerful, flexible queries that support:
 
-- Full-text search
-- Boolean logic
-- Fuzzy matching
-- Proximity searches
-- Semantic search
-- …and more.
+* Full-text search
+* Boolean logic
+* Fuzzy matching
+* Proximity searches
+* Semantic search
+* …and more.
 
 These tools simplify refining searches and pinpointing relevant information in real-time.
 
-## Scripting
-Scripting makes custom data manipulation and transformation possible during search and aggregation processes. Using scripting languages like Painless, you can calculate custom metrics, perform conditional logic, or adjust data dynamically in search time. This flexibility ensures tailored insights specific to your needs.
+### Aggregations
 
-## Aggregations
 Aggregations provide advanced data analysis, enabling you to extract actionable insights. With aggregations, you can calculate statistical metrics (for example, sums, averages, medians), group data into buckets (histograms, terms, and so on), or perform nested and multi-level analyses. Aggregations transform raw data into structured insights with ease.
 
 ## Geospatial Analysis
+
 The geospatial capabilities enable analysis of location-based data, including distance calculations, polygon and bounding box queries, and geohash grid aggregations. This functionality is necessary for logistics, real estate, and IoT industries, where location matters.
 
 ## Machine Learning
+
 Elasticsearch integrates machine learning for proactive analytics, helping you to:
-- Detect anomalies in time-series data
-- Forecast future trends
-- Analyze seasonal patterns
-- Perform powerful NLP operations such as semantic search
-- Machine learning models simplify complex predictive tasks, unlocking new opportunities for optimization.

 Dashboards provide an interactive and cohesive environment with filtering capabilities and controls to explore trends and metrics at a glance.
 
 ### Panels and visualizations
+
 [Panels and visualizations](/explore-analyze/visualize.md) are the core elements that populate your dashboards, enabling dynamic data representation. They support diverse chart types, Interactive filtering, and drill-down capabilities to explore data further. These building blocks transform raw data into clear, actionable visuals, allowing users to analyze and interpret results effectively.
 
 ## Reporting and sharing
+
 You can share your work and findings with colleagues and stakeholders or generate reports. Report generation can be scheduled or on-demand. You can choose from multiple formats (for example, PDF, CSV). These tools ensure that actionable insights reach the right people at the right time.
 Alerting
 You can set up alerts to monitor your data continuously. Alerts notify you when specific conditions are met. This ensures timely action on critical issues.
 
 ## Bringing it all together

 ## Recommendations [population-recommendations]
 
 * Use population analysis when the behavior within a group is mostly homogeneous, as it helps identify anomalous patterns effectively.
 * Leverage population analysis when dealing with large-scale datasets.
 * Avoid using population analysis when members of the population exhibit vastly different behaviors, as it may not be effective.
