Seems like a considerable upgrade from PlanUML (https://plantuml.com/ - which is amazing, but sometimes you just can't seem to be able to align the stuff the way you want too).
In fact, it seems that the code is slightly less readable compared to PlantUML, I should try to recreate some tangled messes and see how the alignment options work!
I wonder when the line is drawn (pun intended) between an low-level UML description language and a SVG-like formatting language with english words in it. :/
