It is "built" around the central ScatterChart(), and flanked by StripeChart() to show the X and Y distribution of both series of Red + Black points, including their respective averages (black line).
X and Y scales are ScaleXY(), including a line that highlights the median of the red + black series.
The median is shown also with the grey area in the lower left corner :
It took me 3 or 4 minutes to create this combination of 9 SFE charts... completely meaningless, but good looking at least !

"[T]his rectangle contains 50% of all the dots on the chart."
That isn't right. 50% of the dots fall to the left of the vertical median line, and 50% fall below the horizontal median line.
You can't even say 25% fall within the gray box, because the slightest correlation between X and Y will result in (for example) different X medians of the upper and lower 50% of the Y data.
Jon, thanks for clarifying this.
My big mistake !
