Family tree / genealogy
Three generations: people, partnerships and descent lines in the conventional genealogy layout.

Why use it?
Kinship is the oldest diagrammed domain — a good test that the layout handles unions and many-child descent.
When it helps
Genealogies, house/lineage diagrams, any parentage-plus-partnership structure.
How to read it
- Boxes are people; horizontal joins are partnerships; vertical drops are descent.
- Read one surname line across the generations before reading individuals.
What you need
- The people
- The partnerships
- The parent-child links
Things to check
- Do not draw descent from one parent when the fact is a partnership's child.
- Dates belong in the boxes; the geometry is kinship only.
Scope of this diagram
Declared kinship rendered conventionally; no genealogical validation rules are applied.
Work with the converted example
- Open the viewer and select
family. Inspect the rendered view and its source. - Open the designer. Keep the selected profile and inspect its legal palette and property controls.
- Change one displayed title or an appropriate data value. Apply the edit and check the resulting diagram.
- Run the verifier and review its diagnostics before moving complete content into review.
- Download your edited DDN source to retain the change.
The example uses the indentation-based ddn-next-1 dialect. The language guide explains reusable definitions, dotted data rows and explicit property blocks.
