DMV Chart
When The California Department of Motor Vehicles mails you a form to renew your car's registration, this lovely chart is included in the envelope.
Issues with this graphic:
-
The color contrast is not accessible for vision-impaired users.
-
Users must work too hard to separate the men’s and women’s data.
-
Body weight is what the user needs to find first, but it is buried.
-
Users will likely not read the chart because it is too crowded.
Process: In Excel, I divided up the women's and men's data from the DMV because they were too difficult to understand in one table.
I selected the men's data, tried many of Excel's native chart types, copied my favorite chart into Illustrator, then adjusted fonts, colors, patterns, and hierarchies.
Next, I tested color contrast using the WAVE Chrome extension. Now a user can easily find their weight and its associated data. I referenced Steven Few and WCAG for best practices in data visualization & accessibility.
Infographic - Carla in a Nutshell
A collection of silly facts about me that I drew in Illustrator. They're all true.
