Vizuly builds upon the great work of Mike Bostock and the D3.js library he has created. Like D3.js, the core framework of Vizuly is open source. This means that you are free to use our library to create your own visualizations for any purpose, commercial or otherwise.
The vizuly framework is very lightweight, and makes it easy to build reusable, encapsulated and theme supported components on top of D3.js. It takes care of all the boilerplate code required to namespace, function-chain, and create event bindings for a component, while giving you the freedom to make it do whatever you want. We have put a ton of inline comments in the source code, and made it as easy to understand as possible, while keeping the code base very small.
Please check it out and let us know what you think.
