This is very interesting! I wonder what the chart would look like if the lengths in each direction represented total lengths of streets in that orientation. Hypothesis for some of the oldest European cities which look like big circles currently - the older parts of the cities which would likely have streets going in all directions are small - so the fat circles would get smaller and we'd start seeing spokes for the newer parts of the cities.
