A linear cartogram of the London Underground, with distance distorted to represent travel time from High Barnet station. While an area cartogram manipulates the area of a polygon feature, a linear cartogram manipulates linear distance on a line feature. The spatial distortion allows the map reader to easily visualize intangible concepts such as ...
A cartogram is a map that intentionally distorts geographic space based on a given variable, usually by scaling features so their size is proportional to their value of the variable. [33] For example, the countries of the world could be scaled proportional to their population.
A cartogram distorts the size and shape of a set of districts according to a variable, but does not dictate the symbol used to draw each district. Thus it is common to symbolize them as a choropleth map. A chart map represents each geographic feature with a statistical chart, often a pie chart or bar chart, which can include a number of ...

A cartogram is a map that distorts region size proportionally, while a flow map represents lines, often using the width of the symbol (a form of size) to represent a quantitative variable. That said, there are gray areas between these three types of proportional map: a Dorling cartogram essentially replaces the polygons of area features with a ...
A medieval depiction of the Ecumene (1482, Johannes Schnitzer, engraver), constructed after the coordinates in Ptolemy's Geography and using his second map projection. The translation into Latin and dissemination of Geography in Europe, in the beginning of the 15th century, marked the rebirth of scientific cartography, after more than a millennium of stagnation.
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. Several automated and manual techniques have been developed to construct cartograms, each having advantages and disadvantages.
