heatmap

A heatmap is a visual representation of data where values are depicted through colors. It helps to quickly identify patterns, trends, and areas of interest or concern within a dataset. For example, in a heatmap showing website traffic, darker colors might indicate more visitors, while lighter colors show fewer visitors. This format allows for an intuitive understanding of complex data by transforming numerical information into an easy-to-read graphic, making it simpler to analyze and draw conclusions at a glance. Heatmaps are widely used in various fields, including finance, health, and marketing.
