Soojuskaardid, also known as heat maps, are graphical representations that display the magnitude of a phenomenon as color in two dimensions. They are widely used in various fields to visualize data patterns and identify areas of concentration or intensity. The concept originated from the need to represent data that varies over space, such as temperature distributions or population density.

In scientific research, heat maps are employed to analyze gene expression data, where different colors represent varying levels of gene activity. They are also used in astronomy to visualize the distribution of celestial objects or the intensity of radiation from different parts of the sky. In environmental studies, heat maps can illustrate pollution levels, temperature variations across a region, or the spread of a disease.

The application of heat maps extends to business and marketing. Companies use them to understand customer behavior on websites, identifying which areas users click on most frequently or where they spend the most time. This helps in optimizing website design and user experience. In urban planning, heat maps can show population density, traffic flow, or crime hotspots, aiding in resource allocation and policy development.

The creation of a heat map typically involves dividing the area of interest into a grid or using existing data points. Each cell or point is then assigned a color based on a predefined color scale, where different colors or shades represent different values. The intensity of the color usually corresponds to the magnitude of the data being represented. This visual representation makes it easier to spot trends, outliers, and areas requiring further investigation.
