A flow map visualization tool
These can be migrations, movement of goods and people, network traffic, or any kind of entities "flowing" between locations.
Spatial interactions are often represented as origin-destination data, meaning that only the origins, the destinations and the magnitudes of the flows are known, but not the exact flow routes.
The goal of this application is to develop a tool that would help to explore and analyze temporal changes in origin-destination data. This is what our novel visualization, Flowstrates, is especially aimed for.
