Computing MSTs of planar graphs for #genuary2021

Genuary is a series of prompts to inspire generated art in the month of January. You can find a list of the prompts here: https://genuary2021.github.io/prompts

Today’s prompt was No loops. This prompt made me think of my datastructures and algorithms classes where I learned about spanning trees which can take a graph that may have cycles and turn them into trees which by nature, cannot have cycles. Today I wrote a program to generate a planar graph and find it’s MST. It’s a bit buggy in that some of the graphs generated aren’t planar and I didn’t write any code to enforce connectedness. It’s close enough though. Hopefully if you’re learning about MSTs right now this is a good visual tool!
