Keep outer generations readable
Open Publish > All reports and charts and select Fan Chart (Ancestor). Choose the person, generations, and shape, then generate the chart. Inspect the outer bands where more ancestors share the available space.
If text is too crowded, reduce the generation count, increase generation widths, or try a fuller circle. Regenerate after changes and inspect the result at its intended print size. Use Large-format charts for printing and export guidance.
