generating cities so one segment connects with all adjacent segments, unlike jigsaw blocks

so im looking to generate cities, but the jigsaw block method, aside from the size limit, won't make a to-be-generated piece be based on every adjacent piece (obviously) My inexperienced idea is that the city would spread from a center structure like a diamond shape and pick from a list of random segments whose streets and roads can connect with all the adjacent ones. | x piece | I piece --------- | | | ofc the city wont generate during worldgen, and it would probably use command blocks and only when the chunks get loaded, but thats ok for me. Any ideas?
