How to Visualize
Migration: more complicated
- should lines/objects be placed in different positions to indicate movement
- should lines represent places that objects/agents move to (what happens if multiple
  objects occupy same place at some moment in time?)
- solution: keep one fixed line per entity, use colors and event symbols to represent move
- colors need not explicitly encode places if # of places exceeds # of colors
