I am trying to build an interactive Pygal worldmap. I posted my code below, but any ideas why the numbers are not showing up when I hover over the map? Thanks!
import pygal
wm = pygal.maps.world.World()
wm.title = "Americas"
wm.add('North America',{'ca': 320161819,'mx': 115405161,'us': 301018101})
wm.render_to_file('americas.svg')
