Most examples work across multiple plotting backends, this example is also available for:
import holoviews as hv
hv.extension('matplotlib')
hv.output(fig='svg')
from bokeh.sampledata.iris import flowers
ds = hv.Dataset(flowers)
points = ds.to(hv.Points, ['petal_length', 'petal_width'], groupby='species').overlay()
points.opts(legend_position='right')
