# Heat Map A heat map is a graphical representation of data where individual values are depicted using colors. It is commonly used to visualize patterns, trends, and variations in data, especially when dealing with large datasets. In a heat map, each data point is assigned a specific color based on its value, and the colors are typically arranged in a grid format.
