AI for Process Maps

Does anyone have ideas or guidance for AI selection/prompts to build swimlane process maps? I’ve been trying to feed it procedures and asking for graphical process maps (very basic example here https://www.qimacros.com/quality-tools/flowchart/ ), but have had no success. The maps can get fairly large so something like excel would be a good format, but I’ll take anything I can get.

I don’t expect the AI to be perfect, but I would like it to get something right. Any help would be appreciated. TIA!
