Exporting a tree-structure as a visual output to another tool from a tool that doesnt provide positional data...
So yeah... Calculate them from the structure. Not that hard to do, right?
But i wasted like a shitton of time because the target tool had the undocumented feature to set everything with a x or y coordinate of 0 (totally valid value...) to 100 / 100. Searched for ages in my code and then just tried adding 1 to everything... and suddenly it worked.
Biggest derp in my recent programming carreer. :/
