After Y-snapping, spouses without shared children can land on top of
each other. Detect these overlaps and move the spouse to the nearest
edge of the generation row without affecting other cards.
Remove post-processing collision resolution that fought ELK's layout.
Keep only Y-snapping (same generation = same row) and grid-aligned
connector Y positions. Add offset drop lines for parents with multiple
spouses so each family unit is visually distinct.
- Add collision resolution pass after Y-snapping: sweeps each
generation row left-to-right pushing overlapping cards apart,
then re-centers the row to prevent drift
- Reset default generations to 3 (up from 4) to avoid layout issues
- Remove generation sliders from chart page for simplicity
- Add sync.sh for deployment to server
Interactive SVG family tree visualization using ELK (Sugiyama) for
layout and D3 for rendering. Shows ancestors, descendants, and siblings
in a single diagram with orthogonal bus-line connectors.
Features:
- Bidirectional tree traversal (ancestors + descendants + siblings)
- Generation-aligned layout with post-processing Y-snap
- Person cards with photos, names, dates, and hover bio cards
- "More ancestors" indicator for persons with hidden parents
- Pan/zoom navigation
- Docker dev environment
