For example, the "color" variable with three categories could be label-encoded as: Label encoding is appropriate when the categories have a natural ordering or relationship with each other, such as in the case of ordinal variables like "small," "medium," and "large." In these cases, the ...

A special case for the bar plot is when you want to show the number of observations in each category rather than computing a statistic for a second variable. This is similar to a histogram over a categorical, rather than quantitative, variable. In seaborn, it’s easy to do so with the ...
