Description
For example in the plot below, I want the plot to figure out what FROM [-20, 20] should be by declaring a midpoint.
SELECT *,
Temp * 1.0 - AVG(Temp) OVER (PARTITION BY Month) AS centered
FROM ggsql:airquality
VISUALISE Month AS y, Day AS x, centered AS fill
DRAW rect
SCALE fill FROM [-20, 20] TO vik

Research direction
Start at the SCALE fill expression in the SQL example and trace how diverging palettes and explicit ranges are handled. Determine the midpoint declaration and its effect on the range, then verify that the example can derive a symmetric range around the declared midpoint.
