Flow maps are visual maps of progressional movement from one place to another. Flow maps can also include thought progression and does not necessarily have to be geospatial. This flow map represents the migration of refugees into Canada between 1990 and 1999. The width of the line represent the population of refugee movement. All lines from the East converge in the Atlantic and form a thick band representing over 90,000 people. These maps are very good for depicting displacement accompanied by another variable such as population.
