I know it's generally possible to split out data viz layout algorithms from rendering engines, but still don't have a clear grip on how that works. Does anyone have any examples?
For, say, a flame graph - would this just be a list of elements and their coordinates? Then it's up to an engine to interpret those coordinates and lay them out.
