HumbleFinance: Dynamic Charts with HTML5, Canvas, and Flotr for Prototype

HumbleFinance is an HTML5 data visualization tool written as a demonstration of interactive graphing in HTML5. It is similar to the Flash tool on http://finance.google.com/. The tool itself is written entirely in JavaScript, using the Prototype and Flotr libraries. It can be used to display any two 2-D data sets of real numerical data which share an axis.
