I am new to Tableau (first day). I have the data below where D* refers to one of three variables that are all correlated against each other. There are 3 instances of each D* variable. When the same variables are against each other, I have put an NA.

I want to make a heatmap from this data where the correlation values (coefficients) are converted to colors. Step-by-step, what can I do to reformat or otherwise the data to achieve this?

If my question isn't framed clearly enough please let me know in the comments.
