Not sure if it's just my browser, but this just looks like a simple visualisation of which found texts where written in which style, when. It says absolutely nothing about the relationship and how the different strands evolved together, nor their locality.
Additionally, it counts modern font inventions as variants of the Latin Alphabet (a somewhat strange but acceptable interpretation) but then proceeds to not show its variants, despite the historic glyphs being shown in multiple variants each.
Turns out: in the end it was my phone browser that didn't show some of the connecting lines due to its Dark Mode Plugin. This is much cooler on Desktop!

I find it lacking.
