Geocart menu class: Miscellaneous
Neither conformal nor equal area

Nicolosi Globular has circular arcs for meridians.
Mollweide has straight parallels and is used for world maps, but meridians within one hemisphere are the same as those on Fournier I.
Azimuthal Equidistant (equatorial aspect) has complex curves for meridians and parallels.
