What about similarly populated cities?
While Neemuch and Nanjanagudu both built increasingly disconnected streets over time, Geidam fluctuated in its street-construction patterns in new street additions. Looking at the full network, Neemuch and Nanjanagudu both became progressively more disconnected, while Geidam fluctuated in connectivity. Notably, Geidam had a more sprawly network than Nanjanagudu in 1975 but the two have since reversed their relative ranking.
