Thanks for the comments, I agree we the key for the map could be clearer (yep it's those lines!). I'm also with you on the bar chart. The pings are on google.com (which resolves to it's local site). And, extra clarification, we're using clo

This was my first attempt at Data-visualisation using d3. I've done a few things with GoogleVis and R, the one is awesome for the web the other is awesome for its flexibility, D3 is awesome for both. I was also pretty much a novice to JS an
