Overview
An interactive visualization exploring the implementation relationships and bootstrapping chains of programming languages, compilers, and runtimes. Discover how languages evolved and influenced each other through visual graph analysis.
Key Features
Interactive Exploration
- Dual Layouts: Toggle between hierarchical DAG and organic force-directed layouts
- Smart Filtering: Filter by relationship type, confidence threshold, and search
- Rich Tooltips: Hover over nodes and edges to see detailed information including evidence sources
- Cluster Visualization: Color-coded by language families (C-family, JVM/.NET, JS engines, functional, systems, scripting)
Visual Encoding
- Node Size = Degree (number of connections)
- Node Color = Language cluster/family
- Edge Color = Relationship type (compiler, runtime, bootstrap, rewrite)
- Edge Opacity = Confidence level (0.0-1.0)
Data Quality
- Automatic validation on page load
- Detects missing nodes, duplicates, dangling edges
- Comprehensive validation reports
- Evidence-based relationship tracking
Export Capabilities
- SVG Export: Vector graphics for publications and presentations
- PNG Export: High-resolution raster images
- JSON Reports: Data quality metrics and validation results
