same density, different #map... moving on from danny dorling's famous cartograms to james cheshire's famous population lines, the first stab involved cobbling census output area centroids into data peaks sized by census 2021 population density... next hope to make each peak's foothills stretch east/west to borough limits (full joyplot) and maybe try curvier mountains
data_mountains is open - what started as an attempt at a geospatial ridgeline plot ended up as a middle-earth lookalike
it turns data values associated with geospatial points into data mountains
enjoyed using #nbdev to make a package out of jupyter notebooks!
data mountains of census 2021 population density in greenwich borough - tenously reminds me this mind blowing india map https://fosstodon.org/@terence/109638760913383378
kensington and chelsea population density data needed square route transformation... there's one OA around chelsea cloisters that has a population density approaching 2 million people per kmsq.
lots of green space in westminster, so trying with basemap (via geopandas explore() function)
a look at population density in an outer london borough, bexley to be precise, an area with one of the least low recycling rates in town
population mountains of southwark. i really like this one as it shows the graduation of people from the riverside metropolis south toward the last vestiges of the great north wood.
greenwich again (my local borough); there's a nice primordial forest here that was almost concreted over in 1994 - you can still make out what would have been a motorway route along the less populated eastern hills and marshes, although the transport minister did compulsorily purchase many homes too https://www.roads.org.uk/ringways/ringway2/eastern-section
here comes lambeth population density, a good companion to southwark, although in this case the 'mountainous regions' don't track the thames river but instead the A3/A23 from waterloo to streatham, giving this a bit more of a misty mountains look.
west from lambeth comes wandsworth, i don't know this area; one of the quirks of being a Londoner is how much of it you never see, though wandsworth definitely includes the site of the album cover with the flying pig and a very nice council data team!
