I started working on a new interactive dataviz yesterday and I am determined that this project is designed and developed using HTML5 rather then Flash. I have already started putting some bits together with Google Charts but just thought it might be useful to list some of the various dataviz open source tools/libraries that I am curently looking at in case there are any other Flash people looking to move other to HTML5 as well.
I am also very keen to hear from anybody else if they have some open source tools to recommend.
