Tuition and Income in the States

Whoa, you might say as you look at this. It's way too funky for me. That's OK; I'm going to show you a new feature in the data visualization tool, Tableau , that I use that will make this all make sense. Hang on. I wondered: Do states with higher median income levels charge more for tuition?  So I began to explore. On each dashboard, median family income is displayed on the top chart, and college tuition on the bottom.  The view starts with four-year publics, but you can change it using the filter.
