Wasn't sure how to render the chart, so I tried Report > Chart tool. Overlooked the ScatterPlot tool.

I started to build this with macros and the Simulation Sampling tool, but realized that it was much simpler (assuming we don't have issues with memory given the number of trials and groups). Also, the Simulation Sampling tool takes a much longer time to run!

Please excuse my old-school scatterplot, as I'm still using 2018.1...
