Orbit Charts, Revisited
Data visualization is not just the art of presenting data to an audience. Upstream from this, you use visualizations in data cleaning to identify defective points, and in exploratory analysis, to identify patterns of interest. Then, you validate these patterns with a more formal analysis. Once confident that you have findings of value to communicate, you worry about making a compelling presentation.
Nick Desbarats and I had a long exchange on LinkedIn prompted by his article Connected Scatterplots Make Me Feel Dumb in Nightingale, the Data Visualization Society journal, on 8/29/2023. What he called Connected Scatterplot is what I call orbit charts, and I have found them helpful, particularly in analysis.

Is SPC Still Relevant? | D.C. Fair & S. Hindle | Quality Digest
“Today’s manufacturing systems have become more automated, data-driven, and sophisticated than ever before. Visit any modern shop floor and you’ll find a plethora of IT systems, HMIs, PLC data streams, machine controllers, engineering support, and other digital initiatives, all vying to improve manufacturing quality and efficiencies.
That begs these questions: With all this technology, is statistical process control (SPC) still relevant? Is SPC even needed anymore? Some believe manufacturing sophistication trumps SPC technologies that were invented 100 years ago. But is that true? We the authors believe that SPC is indeed relevant today and can be a vitally important aid to manufacturing.”
