The Challenge

The “Static Poster” Limitation

Traditional genealogy tools output static, often unreadable PDFs. They fail to capture the living connections or provide a way to easily navigate vast lineages across multiple generations.

Complex Kinship Logic

Calculating relationships like “second cousin once removed” manually is error-prone. We needed a system that could traverse a complex relational graph to provide instant, accurate clarity.


The Solution

Horizontal D3.js Engine

Engineered an interactive D3.js horizontal tree that allows for smooth panning, zooming, and generation filtering. This solves the “vertical clutter” problem, making even 8+ generation lineages accessible.

Intelligent Traversal Algorithm

Built a custom TypeScript recursive algorithm that identifies common ancestors and calculates the exact kinship between any two individuals within the database.

Heritage Analytics & Storytelling

Transformed raw data into narratives through an analytics dashboard. The system tracks demographics and longevity trends, while the “Family Pulse” calendar automates remembrance anniversaries.


Technical Impact

Story-Driven Data

Moved beyond record-keeping to storytelling. The platform makes family history maintainable and engaging for younger generations.

Graph Integrity

100% type-safe data flow from Prisma schemas to D3.js node mappings, ensuring that complex multi-partner and generational relationships remain stable.
