Pro Free
Completely free and open-source as it uses the Apache license.
Pro Just helps building graphs, complements template engines or data-binding libraries
Can be used together with a template engine such as Mustache or Handlebars to display SVG graphics or instead of a static template engine, you can use a data binding or MVC/MV* library, such as Ractive.js, Angular, Mithril or Facebook React.
Pro 3 APIs for the price of one
3 APIs of increasing abstraction:
- Low-level (svg paths)
- Basic shapes (Polygon, Rectangle, Bezier, Sector, Connector etc..)
- Basic graphs (Pie, bar, stock, radar, tree, waterfall, sankey etc...)
There is no magic, you can have as much control as you want on how you define your graphs, source code very readable.
