I am using a fillColor and strokeColor that is fixed right now, and I would rather have this based on the data.
So for example, some circles would be yellow, some green, and some red based on a data attribute or range.
Before I wanted fillOpacity, I was using a different mechanism to color the dots that was based on data, but I assume these two are incompatible or one would take priority. It would be great if they are multiplied together to get the final color. Then I could set the opacity in one, and the color in the other.
