I am a great fan of charts, I really believe that a picture can be worth a thousand words. A good chart can convey a lot of information in a simple and easily digestable form. The most important thing is that the charts should be useful; but a lot of the charts you see on websites are just ugly.
I wanted to create some charts that wouldn't look out of place if they were printed in a magazine. Looking around I found a few libaries but none of them had the look I was after (partly because I didn't really know what I was after). This was just really a fun project personal project so I wasn't limited by anything other than myself.
I decided to see what I could come up with, and knowing I wanted some nice looking graphics decided to choose three.js to render my charts. This would be I could (hopefully) have some nice looking charts with some realistic materials.
After some playing this is what I came up with, the chart is a 3d object that can be rendered at any angle or size, which can make for some interesting effects, there is a simple helper library for adding data to the chart object.
I'm quite pleased with the look, and the interface is pretty easy to use, although it needs some tweaking.
