A while ago, I used Tableau Software to visualize trends in High School Graduates provided by WICHE. I think it was good, but with Tableau's new Story Points feature (in which you create pages of the story you want to tell) I think it's an even better story. If you scroll through these points, you can get a sense of how America has become more diverse, and how those changes vary pretty dramatically by region. That last point, especially, is often lost on people who talk about changing national demographics.
Just like all politics is local, almost all enrollment is too.
So, first, if you want, look at the old version, then take a look at the new visualization below. What do you think?
