Heat maps are a type of data visualization that uses color-coded cells to represent values in a matrix or table. The color of each cell is determined by its numerical value, with darker or brighter colors indicating higher or lower values, respectively. Heat maps are commonly used to visualize large datasets, and they are often used in fields such as biology, finance, and marketing to identify patterns and trends in data.

Heat maps can be used to display a variety of data, including:

• Geographic data: Heat maps can be used to show the density of data points across a geographic area, such as the distribution of crime rates across a city or the popularity of a product across different regions.
• Financial data: Heat maps can be used to display changes in stock prices, with darker colors indicating greater changes in value.
• Website analytics: Heat maps can be used to show the areas of a website that are most frequently visited by users, with darker colors indicating areas that receive more clicks.
• Scientific data: Heat maps can be used to display the results of experiments or simulations, with darker colors indicating higher levels of activity or greater levels of success.
