google style gauges using d3.js

I’ve been playing lately with SVG visualization using the excellent d3.js library. I've originally chosen d3.js because I needed to create highly customized visualizations and d3.js is a great tool for dealing with lower level visualization.

some of the visualizations included gauges. In many of my products I use google's gauges, but in this case I needed to support offline mode, and google's charts require an internet connection. so I decided to go ahead and rebuild it using d3.js.

below are links to the code and example

note: the transition effect of the "pointer" still needs love, feel free to fork or otherwise contribute.

  1. Hi Tomer, I wanted to thank you for sharing. At what point is the label for the min and max written? I can't seem to see that - or is it automatic from d3?
