Click here to see the second version. The second version doesn’t have a color guide, I’d like to do something different than the first version but I haven’t decided how to design it yet. It’s common for people to identify as a developer or designer but not both. Perhaps I’m more of a developer personality type. I also added data for the year 2010.
If you look at the original map that it’s based on, you can see what the colors represent. I slightly modified some of the colors to increase the contrast to make it easier to tell the difference between the different shades. I thought it was especially hard to tell the difference between the different shades of yellow in the original map.
