Categorical data.
Categorical data has only a few values, so is encoded efficiently.
Pandas
documentation on categorical
data:
to make data categorical, you should make a new categorical column: df["B"] =
df["A"].astype('category')
.
The legend="brief"
option to sns.scatterplot
does not work when
the coloring of the points is done with a numerical categorical
variable. Use legend="full"
instead.
