Does anybody reading this thread have suggestions for open source engines/environments to interact/display isometric pixel art? I've looked at a few game engines and haven't found anything well suited for my purpose.

I'd like to be able to generate 3d diagrams of infrastructure maps using the python based mingrammar "Diagrams as Code" approach: https://diagrams.mingrammer.com/docs/guides/diagram presently this can only do 2d SVG.
