Charts, Heatmaps, and Treemaps
These videos discuss a data visualization technique known as a heat map. When we create a two-dimensional data visualization, we call it a heat map. Colors represent the values of the individual cells in the heat map. The color variation may be by hue or intensity. Heatmaps can be very useful for visualizing data in some types of applications. After you have played both videos, identify some possible applications from your experience. Why did you select these data for presentation via a heatmap? How do you think using a heatmap would improve a decision-maker's understanding of the data and lead to better decisions?
