Day 5 was fundamentally a visual puzzle, anyway.
The puzzle involved the intersection of lines, and in part B, this included diagonal lines.
Visualization
There’s no embellishment to this visualization, really, and it’s a pretty direct expression of the prompt. It has some abstract visual interest to it, I suppose.
New Features
No new features that I can recall here. It uses the MapGrid from my helper
library, perhaps I wrote this for day 5?
