Layer Visualization Generator
Generate professional HTML infographics showing depth-dependent features across every biome.
Usage
/layer-viz
Generates a single interactive HTML file with tabs for all biomes.
What it does
Creates layer_viz.html with interactive visualization showing:
Overview Tab:
- ๐ Biome distribution across all 18 biomes (grouped by category)
- Elevation reference: world height, sea level, lava zone, snow line
- Cave fill guide: dry vs flooded vs ice vs lava by biome
- Underground spread: Lush/Dripstone (Y:11-74), Deep Dark (Y:0-31)
- Key depth markers: bedrock Y:0, lava Y:2-10, sea level Y:75, snow line Y:155, build height Y:511
Layer Structure (Per-Biome):
- World height 0-511 with biome-specific surface Y
- Dry / flooded / ice caves and lava distribution by biome
- Snow caps where applicable (mountains above Y:155)
- Color-coded layers with hover details
Depth-Dependent Features:
- ๐ณ Vegetation: tree species, height ranges, densities
- ๐ก Natural light sources: glowstone, crystals, glowmushroom zones
- ๐๏ธ Cave decorations: stalactites, stalagmites, icicles distribution
Interactive Features:
- Tab-based switching with emoji icons
- Smooth fade-in animations
- Hover effects on layers and elevation bars
- Biome-specific color coding
World & Elevation Reference
- World height: 512 blocks (Y:0-511)
- Sea level: Y:75
- Lava lakes: Y:2-10 in every biome; mountains keep lava/water caves up to sea level
- Snow line: stone above Y:155 in mountains converts to snow
- Underground spans: Lush/Dripstone typically Y:11-74; Deep Dark Y:0-31
- Bedrock: single unbreakable layer at Y:0

Implementation
When invoked, run the Python script:
python3 scripts/generate_layer_viz.py
The script at scripts/generate_layer_viz.py is the source of truth for biome layers, surface heights, cave fill, vegetation, light sources, and decorations. See scripts/README.md for more notes.
