Set your sights big When you think you are done, show more

Homework 2 solutions 3D: Color: Schedules: Map  x,y; Time  z Paths = 3d curves; buses = points Rotation, slicing Color: Map  x,y; Time  color Paths = 2d colored curves; buses = points Timeline Schedules: Locations  x (parallel-coord lines) Time  y Paths = connected line segments across par-coords

Visualizing travel plan schedules Timing of : potential Airline flights, layovers, stops driving Events, meetings Timezone changes Multiple stops Group travel! From different locations… Cost
