Geographic Points#

A geographic points plot showing (earthquakes) plotted with their correct geographic coordinates and spatial reference system. This example uses the earthquakes dataset. GeoViews needs to be installed to enable the features option. Earthquake locations are expressed in lat/lon coordinates and are projected with the Plate Carree projection.

import hvplot.pandas  # noqa

df = hvplot.sampledata.earthquakes("pandas")

df.hvplot.points(
    x='lon',
    y='lat',
    title='Earthquake Locations (Bokeh)',
    xlabel='Longitude',
    ylabel='Latitude',
    alpha=0.5,
    color='mag',
    cmap='viridis_r',
    geo=True,
    features=['coastline'],
)
