Flotr2 is a library for drawing HTML5 charts and graphs. It can generate line graphs, bar charts, pie charts and bubble charts. These graphs and charts are generated using HTML5’s canvas and work across several desktop and mobile browsers.
Flotr2 is a fork of the Flotr project without the Prototype library dependency and includes some extra enhancements. It doesn’t rely on any external library and its built-in framework has a great API that you can leverage to build new graph types. Once you provide the data points, the application will automatically calibrate the scale of your axes. Graphs can be zoomed and downloaded as PNG or JPG images.
