Medical Data Visualizer challenge dataframe. HEATMAP

I have created the DataFrame as required, but not able to understand what type of heatmap is required, what should be on x-axis or Y-axis does data needs to be modified accordingly to get that. If anyone can help.

Link to the challenge:

The Replit files contain a folder named “example” and it shows images of valid solutions. So generally you can refer to that if you are wondering how something should look - obviously styling.

Also the point of a heatmap is to show correlation inbetween variables. So x-axis and y-axis are identical and the full set of columns.
