🚨 NEW INTERACTIVE RECESSION TOOL 🚨

In this visualization countries with the highest % of cold homes have the warmest color. That’s poor research communication.
The classic graphic design/color theory improvement would be: to use a continuous gradient from warm to cold. Also the data labels aren’t needed.

One of the most rewarding parts about doing design work for this research project, especially as a PhD candidate, is just how intentional the researchers were. There’s a clear recognition of the humanity in the data and the dignity therein.
During Jim Crow, everything from restaraunts to stores to hotels to pharmacies to gas stations required making safe choices. They shaped every trip a Black person made. We document that history, and you can add your story to it here #CommunityMap: greenbookproject.osu.edu #GreenBookProject #EconSky

Black veterans fought for freedom abroad and returned home to second class citizenship. Traveling while Black during Jim Crow was about survival, mobility, and dignity. The Green Book Project documents that story:
