my updated population map is now live at https://o.blanthorn.com/population-around-a-tile/map/#x=4.6481&y=50.5784&z=6.6381
compare cities with shift-click (or tick the accumulate button on mobile)
all running off a static file server so in theory it should still work in like ten years time
feedback much appreciated here or on the repo https://github.com/bovine3dom/population-around-a-tile/issues

Wait actually it does switch the colour bar too, but only when I also tick or untick the "weight by population" option in the menu... Using Firefox on Android.
