## Voronoi Diagrams in Action

Mini-Investigation: Voronoi Diagrams in Action
Objective:
To understand the dynamics of Voronoi diagrams by manipulating points within a plane and observing the resulting partitioning of the space.
Questions:
1. What pattern do you notice when you move a single point within its Voronoi cell?
2. How does the addition of a new point alter the existing Voronoi cells?
3. Can you create a scenario where moving one point affects the cells of points that are not its immediate neighbors?
4. Explore the impact of having points form a straight line. How do the Voronoi cells arrange themselves?
5. Investigate the minimum distance two points can have between them before their cells touch. What does this tell you about the density of points in a given area?
6. Create a configuration where one Voronoi cell is much larger than the others. Discuss possible real-world implications of this distribution.
7. Challenge: Determine how to place points so that all Voronoi cells are roughly the same size and shape. What applications can you think of for such a balanced distribution?
Activity:
Simulate a delivery service by placing points representing delivery hubs on the diagram. Experiment with the number and location of hubs to find the most efficient coverage for the area. Discuss how Voronoi diagrams can aid in strategic planning for logistics and service area distributions.
