graphique de densité hexagonal

aussi : graphique hexbin

Nuage de points dont le plan est découpé en hexagones teintés selon le nombre de points.

hexbin plot

also: hexbin density plot, hexagonal bin plot, hexagon density plot

Scatterplot whose plane is divided into hexagons shaded by the number of points.

Remède à la superposition des points d'un grand nuage. Distinct de la carte en carroyage hexagonal (hexbin-map), qui agrège un territoire. ggplot2 : geom_hex().

## the proportions of the panel, fixed here at `aspect` (height / width).
