Hi, The original geom_density of both R ggplot2 and plotnine looks weired, becaue it's a polygon. geom_density_line looks well, the only difference is that the geom draws a ridgeline (line with filled area underneath) rather than a polygon. https://wilkelab.org/ggridges/reference/geom_density_line.html will plotnine support geom_density_line ?

Now R ggplot2 can set the outline type ! https://ggplot2.tidyverse.org/reference/geom_density.html
