BubbleTree is a library for interactive visualization of hierarchical data. Originally developed mainly for spending data, the library is now completely independent from the OpenSpending platform. BubbleTree is built on top of jQuery and RaphaelJS.
Please refer to the docs in the wiki pages.
Source code is on GitHub in the bubbletree repo.
