Hi, I know how to enable Labels for Heatmaps:the labels are nicely aligned with the heatmap cells and the values correspond to the column values which are used as color. 

I also know how to enable labels for point plots - where the labels can be chosen independent of the "color" column:

 
Is it possible to combine both approaches:
Heatmap labels, where a column is used as labels which is NOT THE SAME as the column used for color?
Application case:
use a meaningful, normalized value as color [e.g. mortality rate] - but show the actual counts [e.g. Covid 19 victims] as labels.
 
Add-on question:  is it possible to use Character Labels?
e.g. a combination of 
 and
   and   
 
... something like:

so, similar to adding point labels to a heatmap plot, but with the text nicely confined to the heatmap cells?
