How would I generate a value-by-alpha map using QGIS?

[__17]

I have two variables, I'm wondering how would I mask those two variables to generate a value-by-alpha (transparent) bivariate map?

Can someone provide suggestions and ideas? Thanks!

Although they appear less receptive over there...

If you want to try this in ArcMap or Pro, you will have to explain a bit more on what it is you are trying to do since not all people may be knowledgeable in that area.
