I Googled "Vector Networks" and it also seems to be a term that they invented. Figma (their product) is sadly a UI mocking tool and not a vector graphics editor. "Pathfinder" (the tool in Adobe products that calculates fills based on winding order) is notoriously unusable. I'm sure that graphics designers would gobble up tool that had sane path finding.
I'd love to see some literature on how these vector networks work.
