From: From co-location patterns to an informal social network of gig economy workers
Illustration of the steps employed in the preprocessing of the co-location data. Panel a represents a hypothetical scenario with 3 couriers (blue, white, and orange) that have a co-location at 06:26 pm, where just the events from couriers white and orange are filtered to create the network. Panel b displays the same network prior to and after filtering according to the steps described for city C9. The color represents the normalized betweenness centrality, and the size of the nodes is proportional to the degree of centrality
