import pandas as pd
from holoviews.operation.datashader import dynspread
df = pd.DataFrame({'x':[-16.8, 7.3], 'y': [-0.42, 13.6], 'language':['Marathi', 'Luganda']})
points = hv.Points(df, ['x','y'], ['language'])
op = rasterize(points, aggregator=ds.by('language', ds.count()))
dynspread(op)  # Works when dynspread not applied
