A stacked bar chart showing the total count of penguins per species and how they break down by sex. This example uses the penguins dataset.

import hvplot.pandas  # noqa

df = hvplot.sampledata.penguins('pandas')
grouped = df.groupby(['species', 'sex'], observed=True).size().reset_index(name='count')

grouped.hvplot.bar(
    x='species',
    y='count',
    by='sex',
    stacked=True,
    title='Stacked Bar Chart (Bokeh)',
    xlabel='Species',
    ylabel='Count',
)
