I am trying to visualize some LINESTRINGS in a Jupyter Notebook using the Path Object in Goeviews. The Path should be colorcoded by the amount of traffic (see example below). I read the related post Displaying Paths with Geoviews and the given example worked for me.

However, the coloring does not seem to work for Linestrings. Am I missing something? Any help is much appreciated!

import requests
import geopandas as gpd
import json

import holoviews as hv
import geoviews as gv
hv.extension('bokeh')

url = 'http://stadtplan.bonn.de/geojson?Thema=19584'
r = requests.get(url)
data = r.json()
gdf_traffic = gpd.GeoDataFrame.from_features(data['features'])
gdf_traffic.head(1)



#'geschwindigkeit' = 'traffic' in German
%%opts Path [width=500 height=500 color_index="geschwindigkeit"] (cmap='inferno')

gv.Path(gdf_traffic, vdims=["geschwindigkeit"])

If someone still wants to know how to colour the LineStrings, this works for me:

gv.Path(gdf_traffic, vdims["geschwindigkeit"]).opts(opts.Path(color="yellow",line_width=2))
