from plotnine import ggplot, aes, geom_count, scale_size_continuous
from plotnine.data import diamonds

geom_count() makes the point size proportional to the number of points at a location

diamonds.head()

(
    ggplot(diamonds)
    + geom_count(aes(x="cut", y="color"))
)

We can adjust the size range of the points with scale_size_continuous

(
    ggplot(diamonds)
    + geom_count(aes(x="cut", y="color"))
    + scale_size_continuous(range=[1, 20])
)
