A fun little Shiny app inspired by a tweet by @nnstats.
The app is at the nice-enough-to-share prototype stage. If anything looks wonky, odd, or out of place, it's probably just me moving quickly. I'm sure some of the things I did here are good ideas or maybe even good practice, but not everything is, so please take it all with a grain of salt if you're looking to learn something new.
I'm putting the code online because I'd rather share — and to be able to find it again!
