Flow Map
Charles Joseph Minard's map of French wine exports for 1864.

Flow maps in cartography are a mix of maps and flow charts, that "show the movement of objects from one location to another, such as the number of people in a migration, the amount of goods being traded, or the number of packets in a network".[1]

Overview

Minard's map of Napoleon's disastrous Russian campaign of 1812.

Flow maps can be used to show movement of almost anything, such as:[2]

  • What it is that flows, moves, migrates, etc.
  • What direction the flow is moving and/or what the source and destination are.
  • How much is flowing, being transferred, transported, etc.
  • General information about what is flowing and how it is flowing.

In contrast to route maps, flow maps show little aside from the paths from one point to another.[2]
