Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Supported chart types are area, bar, column, scatter, pie, donut, line, stacked, grouped, force-directed, streamgraphs and parallel coordinates charts.

I woke up this morning and wanted to play with the HTML5 audio API and experiment with how data from it could be visualised. So I set to work and within a couple of hours had set up a very rudimentary graphic equaliser kinda-thingy. You’ll need Firefox 4 beta to see it, but if you have Chrome or Safari, the music is cool anyway ;)

I need to look into making it a little smoother, I think that the way I’ve applied the fast fourier transform to the data may be a bit dodgy because the bars jump around in a way which is not necessarily what you’d expect.

Over the next few days/weeks/when I have time, I’m going to play with how else the data might be visualised.
