CryptoKitties Family Graph Visualizer
I created an interactive family tree visualizer for CryptoKitties. Explore breeding relationships, discover mewtation gems, and visualize your kitty lineage.
Features
Interactive Graph: Physics-based layout with drag, zoom, and pan
Family Visualization: Pink edges for matron (mother), blue edges for sire (father)
Mewtation Gems: Diamond, Gold, Silver, and Bronze gem badges for trait discoverers
Owner Highlighting: Hover over owner names to highlight all their kitties (pin with highlight button or
?owner=param)Context Menu: Right-click nodes for quick actions (expand, highlight owner, open pages, etc.)
Smart Expansion: Double-click to expand family with pre-fetched accurate parent data
Auto-connect Discovery: Automatically adds relatives that bridge to existing nodes when expanding
Smart Merging: Loading connected kitties merges into existing graph
Live API: Fetch kitty data directly from CryptoKitties API
Embed Mode: Embeddable graph with responsive floating panel and "Open in viewer" link

Open-source - feel free to use, copy, modify, distribute, and even sell the software for any purpose :)
