# This also gives better context to why the parameter passed in to `broad_station_gdf`
# is named `get_fill_color` while the parameter for the other two is `get_color`. This
# is because they're rendered as separate deck.gl Layer types, and the point layer also
# has a `get_line_color` parameter for rendering the outline of the point.
