Heatmap

A heatmap is a graphical representation of data that uses color to represent the magnitude of a value. The data is typically represented by a two-dimensional matrix, with the rows and columns representing the different variables. The color of each cell in the matrix represents the value of the variable at that point.

Heatmaps are often used to visualize data that has a high degree of correlation. For example, a heatmap could be used to show the relationship between the temperature and humidity in different parts of a city. The warmer the colors, the higher the temperature, and the darker the colors, the higher the humidity.

Heatmaps can also be used to visualize data that has a high degree of variability. For example, a heatmap could be used to show the distribution of income in a population. The lighter the colors, the lower the income, and the darker the colors, the higher the income.

Heatmaps are a powerful tool for visualizing data. They can help to identify patterns and trends that would be difficult to see in other types of graphs.
