How to create a venn diagram where sections are colored by the values of a continuous variable (like a heat map)?

Question

I'd like to create a Venn diagram in R, where the sections are colored based on the value of a continuous variable. Each venn diagram section has its own value (ranging from 0-1), and this value is DIFFERENT than the count variable also displayed in the diagram. I have three categories (and all of their intersections) to display (a total of 7 values for the continuous variable).

Does ggVennDiagram allow for this?

You can use the euler function with fills defined as you wish. Here is an example with colors, but you could use a gray scale.

col<- c("red","blue","green","yellow","purple","black","white")
test <- plot(euler(c("A"=79,"B"=378,"C"=134, "A&C" = 55, "A&B" = 176, 
                     "B&C" = 110, "A&B&SC" = 101)),quantities = TRUE, 
fills= col);
