What is a heat map graph?

What is a heatmap? A heatmap (aka heat map) depicts values for a main variable of interest across two axis variables as a grid of colored squares.

1 Answer. The dendrograms along the sides show how the variables and the rows are independently clustered. The heat map shows the data value for each row and column (possibly standardized so they all fit in the same range). Any patterns in the heat map may indicate an association between the rows and the columns.
