In web applications developed now days a lot of the logic that previously
resided on the server side is now being implemented on the client side.
This is especially true for information presentation, components such as
trees and columnlist makes it possible for users to interact with the
application, or web site if you wish, without contacting the server.
However the ability to present data in a graphic rather than textual
format has been quite limited, unless a plugin is used or an image is
requested from the server.
That's where this component comes in to place, it allows various forms
of charts to be created, without any additional plugin, and without
using images.
