Didn't really do the graphs that i thought it would do. Good for simple graphs, like for a presentation

@FantasyGen - AI Fantasy Map Generator

It's hard to know the capabilities of this system as only 1 credit—good for 1 generation—is on offer without a subscription. The generated map (Fantasy World / Continent) was nice, but it would be better if other types could be trialled as well.
