Heatmap is a powerful data visualization chart that employs a color-coded system to represent the intensity or density of data points across a two-dimensional plane or even in a multi-dimensional space. It visually communicates the magnitude of values through a gradient color scale, allowing viewers to intuitively understand the distribution patterns, concentrations, and variations in the underlying dataset.

In a Heatmap chart, the X and Y axes typically denote different categorical variables, and each cell within the grid is assigned a color that corresponds to the value associated with the intersection of those variables. Darker colors generally indicate higher values or greater concentration, whereas lighter colors represent lower values or lesser density. This form of representation makes heat maps incredibly useful for spotting trends, clusters, outliers, or areas of interest in large datasets.

Heat maps are widely employed in various fields, including geographical data analysis to show population density or traffic flow, website usability studies to track user clicks and interactions, financial markets to visualize price movements, biological sciences to display gene expression levels, and more.
