 | stats  sum(Sales) as Sales by Widget,Region
 | table Widget, Region,Sales

Creates a table with unique widget, region pairs as rows, sum(sales) as a metric.
Expected X axis with widget names (WidgetA, WidgetB, WidgetC), Y axis as region names (North, South, East, West), bubble size as sum(Sales).
Observed all the bubbles at 0,0 and both X and Y axis is numeric.

One other answer suggested adding

        <option name="charting.axisX">category</option>
        <option name="charting.axisY">category</option>

Would specify the non-numeric option, but didn't work for me.

The few answers for Bubble (I guess Scatter will be the same) was from way back, tried them but didn't work.
In desperation I tried

        <option name="charting.axisX">Widget</option>
        <option name="charting.axisY">Region</option>

too, but to no avail...
