French demography as bubbles

Related blog post [fr] : datagistips.blogspot.fr/2016/03/statistiques-et-bulles-di...

 

Circle packing applied to the population census stats

 

I experimented circle packing technique as a way to put statistics on a map

 

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

 

The demography stats are integrated as a rosette with 6s petals as quinquennal categories

 

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

 

Data :

- GéoFLA IGN for the contours,

- 2012 Pop. Census by INSEE for the pop. stats

 

Made with R for computation & QGIS for design
