The first few graphs are impressive, it does a much tidier job. The Go queue one is objectively worse - the other versions keep services and users grouped together, as well as a left-to-right flow. The TALA version makes it look more complicated than it is.
The post does highlight that in the introduction:
> It doesn't do DAGs as well. I often find myself preferring Dagre or ELK when I want a long flowing graph.
I thought "how bad could it be" and I was quite surprised :)
That's spectacularly obfuscated in comparison to the rest.
TALA is terrible at respecting the "direction: <up, down, left, right>" directive. It should choose an aspect ratio based on the direction, but instead it is trying to make the diagram as square as possible.
