python - GeoPandas and Bokeh extract xs and ys from data - WorldMap

Question

I found this post on Geopandas and bokeh extract xs and ys from data

What I need is basically the same thing but for the map of the whole world (extract XS and ys from GeoPandas and convert into bokeh readable format). I am struggling with the fact the world data has both polygons and multi polygons.

If anyone can help, that would be much appreciated. Thanks!

This is how you can run a GeoJSON using pandas GeoJSONDataSource like I mentioned in my comment.

from bokeh.models import GeoJSONDataSource
from bokeh.plotting import figure, show, output_notebook
import geopandas as gp

output_notebook()

world = gp.read_file(gp.datasets.get_path('naturalearth_lowres'))
geo_source = GeoJSONDataSource(geojson=world.to_json())

p = figure(title='World', tooltips=[('Country', '@name')],
           x_range=(-180, 180), y_range=(-90, 90), 
           x_axis_location=None, y_axis_location=None,
           plot_width=1000, plot_height=500
          )
p.patches('xs', 'ys', fill_alpha=0.4, fill_color='grey', 
          line_color='black', line_width=0.5, source=geo_source
         )
show(p)

Output
