among data in ways that help viewers recognize, engage in, and think critically about their important relationships."

To create a close cognitive connection between conceptual and graphic content, I selected a color palette consistent with the typical conception of a desert - yellow representing the more barren areas, and green representing health and life. To contrast the green, healthy food sources, I also included red, unhealthy food sources as an instinctive counterpoint.
I then chose to generate a set of Voronoi diagrams which can be layered over the location points in order to emphasize the distribution of food sources. To guide viewers, hover states reveal an explanation of the Voronoi lines: "Partitions the map so that each cell contains one healthy food source and every point within the cell is closer to that source than to any other."
Toggling between the Voronoi lines associated with healthy and unhealthy allows for a comparison between the distributions of each. It becomes clear that healthy food sources are more evenly distributed throughout the city, whereas the unhealthy sources are more concentrated to particular areas.

To emphasize the differentiation between the three income levels, each category - Low, Medium, and High - appears individually before combining to complete the map.
