Interactive Heat Maps

[Alex Harsanyi]

A few days ago I posted about adding maps to the DrRacket REPL -- while a nice demo, this is not why I implemented the `map-snip%` object.  The reason I implemented it is because I wanted to add maps to an interface which was designed for displaying plots produced by `plot-snip`.   While this is not technically a racket topic, the application itself is written in Racket and I think it is a nice showcase of Rackets' GUI capabilities, so here is a demo:

There is quite lot going  on "behind the scenes" here, and I covered some of the topics in this blog post, but if you have any questions I am happy to answer them: https://alex-hhh.github.io/2019/09/interactive-heat-maps.html
