Three design suggestions: 1. Pie charts need to die in a fire. I'm Tuftian like that. :) 2. The "scratched" fill on the bars makes it really hard to "read" them; solid colour would be much much better in my opinion. 3. I don't think bars are a good choice to display developments over time (for a non-discrete domain, if you will). I think line charts are much better, but you could probably get the best of both worlds by combining both visualizations into one. Please don't take this the wrong way, but I am not blown away by the design. d3.js has really spoilt me in raising the bar so high like that, but I am sure that your general demographic will find it fine. Still, it might be worth to draw some inspiration by some of Bostock's blocks at http://bl.ocks.org/mbostock http://bl.ocks.org/mbostock. .05. :)
