What is the proposed idea/solution?

Currently, Maps extension (which utilizes Google Maps API) supports dynamic marker size "by field"'; however, this field may only be a static `Number` (or equivalent such as `Rating`). A computed number such as `Count` should be eligible as a source field.

How does is solve the user problems?

In my case, I am trying to size markers based on a `Link` to a separate table. I wish to count the number of linked records as the determinant of map market size.

How was this validated?

Tested with four columns: Number, Single line text having number values, Rating, and Count of linked record. Number and Rating are eligible fields for `by Field` map marker size configuration option, the others are not (grayed out).

Who is the target audience?

Any user of Map extension.
