Python: easy way to create worldmap data distribution

I'm looking for an easy way to create a worldmap in python. For example, let's take the following country data:

world_data = {
  'af': 141,
  'bd': 5,
  'by': 2,
  'cn': 10,
  'gm': 90,
  'in': 43,
  'ir': 314}

      

        
        
        
      

    

Is there any easy way to create a world map with custom coloration and color threshold for this data?

I am currently using pygal (see below). Unfortunately I didn't find a way for the pigal to print a color legend or define thresholds for coloring.

worldmap_chart = pygal.Worldmap()
worldmap_chart.add('data', world_data)
worldmap_chart 

      

        
        
        
      

    

Any help is appreciated
