This one looks like a graphical Markov chain generator. At this level of detail it's hard to tell if the generated city is implausible, because cities are shaped by many factors that aren't visible on the map (history, soil, location within larger region, economic and social policies, etc.) So a clump of buildings near a river avoiding mountains is a good guess every time.
