I've mapped a few American cities on a km square grid, with the same colors as that link. Some details most won't care about:

Using block groups, I missed some water area unlike the link (I'd rather skip water but it wouldn't match their link). But if I use census tracts, some low density areas will have no census tracts in them — the census tracts are larger than a square kilometer; so I was left with a lot of blank spots. Census tracts without water area inflated the weighted density by about 7%. Census tracts vs block groups made little difference, since I was regridding per square km.

I didn't use the same map scale as the chartingtransport though the density colors are the same.

Use the legend from to see what density level each color refers to. X and Y labels refer to longitude and latitude. All use the US Census defined urban area boundaries. New York City:



San Francisco Bay Area:

Los Angeles:

San Diego:

Bar chart similar to the ones in chartingtransport, denser part of NYC is very similar to Paris. NYC almost certainly has the largest density range of any developed world city.
