Heatmaps are visual representations of data where values are depicted using color gradients. Typically used in various fields such as data analysis, website design, and geographic mapping, heatmaps help to illustrate patterns, trends, and intensity levels in a dataset. For example:
- In website analytics, heatmaps show where users click, scroll, or hover most frequently, using colors to indicate areas of high and low activity.
- In geographic information systems (GIS), heatmaps visualize the density of events or phenomena across a geographical area, with warmer colors often representing higher concentrations.
By converting numerical data into easily interpretable color patterns, heatmaps allow users to quickly identify areas of interest and make data-driven decisions.
