graphical cartogram: maintains neither shape, topology or location; instead using non-overlapping geometric shapes (e.g. circles or squares) to represent the mapped variable gridded cartogram : uses repeating shapes of the same or different size to create a tessellated representation of the mapped variable

cartogram: a thematic map that scales the size of an enumeration unit proportionally to the represented value choropleth map: a thematic map that uniformly colors each non-overlapping enumeration unit according to the represented value
