From: From mobile phone data to the spatial structure of cities

Histograms of the coefficients < Dper >/< Dint > (a) and < Dmed >/< Dint > (b).
While the spatial features of intermittent and intermediary hotspots are similar, the main difference between cities lies in how the permanent hotspots are distributed in space. This figure was created with R and LibreOffice Draw.
