A size variable is a visual variable that defines the size of a symbol based on a numeric data value returned from a field or expression. This does not apply to renderers with fill symbols. To visualize a polygon layer by size, you should use a marker symbol, which will be rendered at the centroid of the polygon.

Size visual variables require the following:
- A reference to a data value either from a field name, or an Arcade expression.
- At least two size stops that match data values to sizes. The sizes of symbols with data values between the designated stops are interpolated linearly.
