Heat Map

A heat map is a graphical representation of data where the individual values contained in a matrix are represented as colors. Heat maps are used to visualize patterns and trends in data, and to identify relationships between different data sets. The colors are typically used to represent the magnitude of a value, with warm colors (such as red or yellow) indicating high values and cool colors (such as blue) indicating low values. Application areas include data visualization and data analysis to quickly and easily identify patterns and trends in large datasets.
