Making charts quickly the web way

For my thesis I need to make some charts of course. Trying to do it with a spreadsheet app such as OpenOffice or Google’s quickly annoyed me as I couldn’t figure out how to annotate each chart bar. I immediately recalled that there are great JavaScript libraries that draw on HTML5 canvas, and found jQuery Visualize plugin. It’s pretty awesome how you just need to make a plain table and it will do the rest in a one line call.
