the poolData Dive
Bring a file. Pick a shape. Tune it until it tells the truth.
The last step: you choose what to throw away. Nothing is uploaded. Every knob here changes what you see, never the file. What leaves is a picture, a project file, a hand-in page, and what you noticed.
The default view should carry the finding. If someone has to hover to see the point, it is not finished.
With this on, the stage stays covered until you write what you expect. Guessing first is what makes the chart able to surprise you.
