Types of Flow Maps

Types of directional & pattern of flow

1. Radial 
2. Network
3. Distributive

Radial

Types on direction & pattern of flow

one source to multiple destinations: 1 way flow

quantitative

Network

types of direction & pattern of flow

interconnecting of multiple locations; 2 way flow

qualitative or quantitative 

Distributive 

Types of direction & pattern of flow

multiple sources to selected destination

quantitative 

1. Line Scaling
1. proportional line width
1. width of widest flow lines(s)
2. smallest flow line calculated to ensure will be visible
2. range grading
2. Line Symbols
1. overlap lines -> smaller lines should overlap larger ones
3. Figure Ground
1. Flow lines = visual hierarchy
2. solid lines = best
3. translucent lines okay
4. minimal base map info recommended
4. Legend Design
1. 4 common legend designs
1. key values
2. stairstep design
3. range graded
4. ruled line
2. units of mapped quantity
3. identify type of phenoma

1. Degree Centrality
1. where & how connected
2. Betweenness Centrality
1. high betweeness = great influence
2. shortest paths = higher betweeness
3. Closeness Centrality
1. measure of closeness of nodes
2. shortest paths

1. Edge Features {relationships}
2. Junctions Features {people aka nodes}
3. Connectivity
