What does it look like when you take ✨ Kotlin Notebooks ✨ and solve #AdventOfCode Day 3? Well, it looks like this! @volebamor created this viz live on our stream that just finished. 🎨

Nothing even comes close to @Kotlin Notebooks when doing this stuff.

And will be improved in the nearest Beta4 release!
