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.
- 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
