cities = geocode_cities(['Berlin', 'Sankt-Peterburg', 'Washington', 'Mbarara'])

The space between the point and the text is different for each object and gets bigger closer to the poles.¶

ggplot() + geom_livemap() + geom_point(map=cities, color='red') + geom_text(aes(label='found name'), map=cities, nudge_y = 5, color='red')

When zooming with point scaling on, the text stays in the right place, but it does not scale.¶

ggplot() + geom_livemap() + geom_point(map=cities, color='red') + geom_text(aes(label='found name'), map=cities, nudge_y = 1, color='red')

When zooming with point scaling off, it's good that the text doesn't scale. But the distance in pixels between the point and the text changes.¶
