- Node I2Djs - is an Open source nodejs framework for server side 2D graphics. Based on Canvas.
+
+# What is node-i2djs?
+
+node-i2djs is a node module for rendering canvas based 2D graphics. node-i2djs provides a declarative and virtual Dom based model that helps in efficient rendering. node-i2djs is built on top of the node canvas module. node-i2djs also provides APIs to create and export the content in different media formats like  Images/PDFs.. etc.
+
+# What does it provide?
+node-i2djs declarative approach provides an easy way to define different types of geometrical entities, as supported in SVG. It also enables pixel manipulations, multimedia support, PDF creations.. etc
+
+It provides API's to create, access, modify, and delete graphical entities on canvas. Functionalities such as Data Joins (Join-Actions) help in associating/binding data with graphical elements and their manipulations.
+The following node-i2djs features helps in achieving efficient and scalable rendering:
+  - <b> Declarative Rendering: </b> Simple syntax and semantics by abstracting complex native syntax. Inline with client - I2Djs framework.
+  - <b> Virtual DOM tree:</b> node-I2Djs (all contexts) implements a mini Virtual DOM tree, which is a Javascript object representation of the corresponding DOM. Helps in keeping the state intact and enable operations such as update, addition and deletion as per the requirements.
+  - <b> Join-Actions(Data Joins):</b> node-i2djs Join-Action mechanism helps in binding the data to the graphical elements by defining the actions - Enter, Update and Exit. It provides flexible handlers to manipulate data and trigger corresponding actions in an optimal way.
+  - <b> Multi page PDF / media support:</b> node-i2djs lets u export the content in different media formats. It also provides exclusive apis to create multi page graphical PDFs.
