Part time development work needed for D3.js.
Here is a small test to see if you are able to understand the assignments. Go to http://bl.ocks.org/mbostock/3885304, and make the bars horizontal. Then add some effect on rollover that is unique to each bar. For example, add a tooltip or change the color of the bar according to it's value. Do whatever you want, just show me that you can manipulate D3.js objects.
I am a D3.js expert and live in Silicon Valley. I will be able to help you if you get stuck. If you do well, I will give you more fun projects!
