Dongshan in context
The chart above shows SNDi trends for new street additions (left panel) and the entire network (right panel), with Dongshan plotted against Jiangsu and China. The SNDi of new construction in Dongshan was at its lowest in 1991-2005, compared to Jiangsu which peaked in 1976-1990 and China which followed a zig-zag trend with an overall increase. Most recently, Dongshan's incremental SNDi rose from 4.06 to 4.57 between 1991-2005 and 2006-2020.

What about similarly populated cities?
In new street additions, Dongshan built increasingly connected streets from 1975 through 1991-2005, then shifted to more disconnected patterns, while Isale built increasingly disconnected streets over time and Ramgarhwa fluctuated in its street-construction patterns. For the full network, Dongshan became progressively more connected, while Isale became progressively more disconnected and Ramgarhwa grew more disconnected from 1975 through 1976-1990, then improved. Notably, Dongshan had a more sprawly network than Ramgarhwa in 1975 but the two have since reversed their relative ranking.
