Why larger TreeLines take longer

When TreeLine arranges your family, it isn't simply drawing names in a list. It is solving a spatial puzzle: every person must be placed in a row that respects their generation, their relationships, and the visual flow of the chart. Connectors must not cross unnecessarily, branches must read clearly, and the overall layout must feel balanced.

For small families — say, under 200 people — this process completes in under a second. For medium families the optimiser runs for a few seconds. For larger families, the search space grows quickly, and TreeLine may take a minute or more to find a good arrangement.

The result is worth the wait: a carefully optimised layout that would be impossible to achieve by hand.
