Statistical Map

Any kind of data that can be expressed numerically and varies in quantity from place to place can be mapped. This is the basis for statistical mapping. Point, line, and area symbols are used in statistical map

Pictoral of a Cartogram


A cartogram is a type of graphic that depicts attributes of geographic objects as the object's area. Because a cartogram does not depict geographic space, but rather changes the size of objects depending on a certain attribute, a cartogram is not a true map. Cartograms vary on their degree in which geographic space is changed; some appear very similar to a map, however some look nothing like a map at all. There are three main types of cartograms, each have a very different way of showing attributes of geographic objects- Non-contiguous, Contiguous and Dorling cartograms.


Flow Map

Flow maps are used to show the movement of objects from one location to another. The designer of this visualization used our system to produce a flow map which then they mapped to a globe. It appears in the UK Interdependence Report.

Isoline Map




An isoline map is a map with continuous lines joining points of the same value.

Proportional Circle Map


Based on correlations between values and size; Proportional Circle maps are illustrations using circles to display values depending on the amount or size of the value. The higher the data value the bigger circumference of the circle. This work portrays population size among various cities in Indonesia.

Cloropleth Maps


Derived from Greek origin: Cloropleth means "Cloro -place, pleth - value"

A type of thematic map; Cloropleth maps are illustrations of areas, either colored or shaded, that reflect values of a phenomenon or to display classes of values. Cloropleth maps are arranged in various ways depending on the values that are to be interpreted; either quantative or qualitative area variables.
