If took more code to animate this than it did to solve the problem...
Looks very nice for the test data:
And...okay...for the live data:

An unofficial home for the advent of code community on programming.dev! Other challenges are also welcome!
Advent of Code is an annual Advent calendar of small programming puzzles for a variety of skill sets and skill levels that can be solved in any programming language you like.
Everybody Codes is another collection of programming puzzles with seasonal events.

I like the coloring, really cool!
Thanks, 'Tis the season.
Its very festive :)
That certainly doesn't reflect my mood today.
Thats cool! What are the colours meant to signify?
Christmas, I guess :) (I just pick a random colour each time a roll is removed)
Day 7 - Colourised, single image.
Video of each path (for the short example, dont think i can do the long one) https://youtube.com/shorts/jLpiUOSIiNw
That's day 7, right?
Its all a blur...

Colorised, but filling in from least photons to most: https://youtube.com/shorts/McM1yIn5UCw
Showing the of it filling in a bit clearer (or less clearer, i dunno): https://youtube.com/shorts/dBYAdRyhCLU
Apparently this is ~~wrong. Not sure what I'm missing here.~~ correct, my code was borked I guess (maybe an overflow or something?).
First time I've seen a visualisation before solve :D
I took one look at pt2 and noped out, its a later problem I think...
Correction, turns out doing it entirely in Excel was the answer for me. The points I found were correct, but the area calculation in my code was wrong.
I had to visualize it before I could even attempt to solve it. Still did it mostly intuitively based on the visualization.
Ha, love an excel solution, please do share it in the solutions thread!
The graph of Day 11, created with very little effort using the dot utility of graphviz. Because of a stupid parsing error I ended up with a cyclic graph, so this visualization helped in debugging.
I was meaning to do that as well, but forgot. Nice!
Apart from day 4 not much to visualise so far this year :/
Yeah, Im hoping it picks up. No mazes yet :(
Day 7 (zoom to full screen): https://lgbt.earth/i/web/post/903381501524320591
I can probably improve this a lot, but I was afraid I'll be too lazy after getting this far, so posting as is. Still, lmk if you have any suggestions :)
Squeezing all spaces out of the grid (and plotting at right-angles to the other visualisation here) gives this evil shape, which will doubtless haunt my dreams tonight.
Day 8: https://youtu.be/QiezRG4jiUM
Getting pretty close to having written my own game renderer, only slower and worse :D
I made a quick visualisation of my input for day 9 with matplotlib. Still haven't solved part 2 though.
Scales got a messy :D
I know I'm late, but I'd thought, I'd share some of my day 12 visualizations I wanted to see.
