Hello fellow racketeers!  
[Here](https://github.com/TrueQueenBee/complex-analysis) is a small tool I created for drawing and analyzing [complex-valued equations](https://en.wikipedia.org/wiki/Domain_coloring)

In the future it should be available as a package under the name `domain-coloring`

Usage instructions and additional information can be found [here](https://github.com/TrueQueenBee/complex-analysis#readme)

Hope someone finds this interesting!

Thank you for making this.

When I saw it originally I thought It was built on the [Plot library](https://docs.racket-lang.org/plot/index.html) because they both have interactive zooming functionality but your version is more interactive, and takes place in a separate window, instead of an interactive snip in DrRacket.

I **really** want to add this to the nascent [Racket Plot Cookbook](https://github.com/Racket-Cookbooks/Plot-cookbook) - I’ll have to come up with a related projects section!

Thank you again for making and sharing this!

Stephen

Note to self - add other related projects to [Racket Plot Cookbook](https://github.com/Racket-Cookbooks/Plot-cookbook) related projects section as well:

> **[sawzall-lib](https://pkgs.racket-lang.org/package/sawzall-lib)**

> A grammar for data wrangling (no documentation)

> **[graphite-lib](https://pkgs.racket-lang.org/package/graphite-lib)**

Am I missing any?
