Google Bullet Graphs

Trevor Lott of www.DealerDiagnostics.com, a service that provides performance reports for auto dealerships, wrote to me recently. Here’s what he said:

I’ve been a fan of your work for several years and have always been impressed with your willingness to share, be it innovations, ideas or feedback. It’s only fitting that I had you in the back of my mind when I was testing the Google Charts API a few weeks ago to explore the potential of the web service to create bullet graphs. I’m happy to report that it’s possible but wanted to take it one step further: to promote bullet graphs and help to increase their accessibility. To that end, I wrote up a quick guide to creating bullet graphs using the Google Charts API. Please consider it a small tribute for what you’ve given to me and the data visualization community over the years.

I appreciate Trevor’s kind tribute—especially the fact that he delivered it in the form of a practical solution to a real need. If you’re interested in producing bullet graphs using Google Charts API, take advantage of Trevor’s fine work, which he’s provided as a simple series of clearly explained steps. You’ll find it in Trevor’s blog.
