The Seaborn heatmap is a simple visual that allows you to display tables of data through color. This Seaborn heatmap tutorial motivates the use of heatmaps and explains how to make a heatmap in Python Seaborn. Using an example pandas dataframe, I describe the basics of building a Seaborn heatmap, how to transpose a heatmap, and how to use pandas and Seaborn to create a correlation matrix heatmap. I discuss the importance of choosing a good color palette and how you can change the Seaborn heatmap color. I show you how to add Seaborn heatmap annotations as well as how to change the format of your annotations to remove scientific notation. Lastly, I provide additional styling tips to change the Seaborn heatmap tick labels and draw lines between the heatmap rectangles.
