Once constructed, cartograms are often used as a base for other thematic mapping techniques to visualize additional variables, such as choropleth mapping. However, ratio numbers can also be calculated from two non area-related values, but the absolute numbers somehow have to be in relation with their reference area, as it is styled depending on . A Cartogram purposefully distorts the size of areal features proportional to a chosen variable, such as total population, and thus may be thought of as a hybrid between choropleth and proportional symbol maps. brainly.in/question/12763166 answered by Harpreet2223.
