Before drawing any chart, walk through five steps: name the single fact it communicates, check if prose can carry it instead, count the conditions being compared, decide what the reader's eye needs to do, then audit for AI tells. The tree was built across four rounds of refinement on a single swimmer's data, and each step kills more charts than it produces. The chart exists to communicate a fact the prose cannot — usually a pattern across many data points the eye reads faster than words can describe.
