This exercise has two parts:
Part 1: The following figure shows the paths that Napoleon’s troops move to and retreat from Moscow:
Suppose we also know the exact date (year/month) for each dot in the map and the number of soldiers at that date.
Please design a visualization to encode the above information (i.e., time and number of soldiers).
Part 2: Given the HKUST campus map and also the flow from one location to another location in any hour (e.g., 10am - 11am, 154 people move from library to UG hall 1), please design a visualization to show the flows from the top 5 most popular flow-out locations to other locations in a given hour. How to deal with the flows between locations with the same (x, y) position in the map (e.g., from library to LG7)?
