The following trace types support attributes named geo or mapbox, whose values must refer to corresponding objects in the layout
i.e. geo="geo2" etc. Note that attributes such as layout.geo2 and layout.mapbox etc do not have to be explicitly defined, in which
case default values will be inferred. Multiple traces of a compatible type can be placed on the same subplot.

 The following trace types are compatible with geo subplots via the geo attribute:

 - scattergeo, which can be used to draw individual markers, line and curves and filled areas on outline maps

 - choropleth: colored polygons on outline maps

 The following trace types are compatible with mapbox subplots via the mapbox attribute:

 - scattermapbox, which can be used to draw individual markers, lines and curves and filled areas on tile maps

 - choroplethmapbox: colored polygons on tile maps

 - densitymapbox: density heatmaps on tile maps
