In cartography, flow maps 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".
- 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.
