Transportation modes used by Paris citizens as bubbles

Circle packing + pie charts applied to the transportation modes in Paris at the IRIS administrative sub-units.


I experimented circle packing technique as a way to put statistics on a map with fine detail.


This prevents overlapping, although it is not always spatially precise, depending on the scale of study.


The socio-pro stats are integrated as a rosette with 6 petals for the 6 categories : farmers, workers, managers, employees, intermediate professions, craftsmen & company directors


The scale_exp function was used to determine the petal length, after being ported to R.


Data :

- Contours...IRIS for the contours,

- 2012 Pop. Census by INSEE for the socio stats

- OpenStreetMap for the subway data

- ROUTE 500 IGN for the district contours


Made with R for computation & QGIS for design
