1. Hexagonal Grid & Cell Physics
https://observablehq.com/@lloydrichardsintern/hive-diagram-builder
Interactive Observable notebook that draws perfect hex grids and labels them; the exact math (hex-to-pixel, pixel-to-hex) appears verbatim in the GPT-5 output.
https://www.redblobgames.com/grids/hexagons/
Canonical reference for axial & cube coordinates used in the simulator.
2. Swarm / Agent Movement
https://github.com/mourner/tinyqueue
Ultra-light priority-queue implementation; GPT-5 uses it for A* path-finding of every worker bee.
https://github.com/bgrins/javascript-astar
Another A* lib inlined (with MIT header intact) to route bees from nectar sources back to vacant cells.
3. Real-time Canvas & Particle Animation
https://p5js.org/examples/simulate-particle-system/
The bee “wiggle” trail is a stripped-down p5 particle system rewritten in vanilla <canvas> for one-file portability.
https://threejs.org/examples/#webgl_buffergeometry_drawrange
(Optional) If the user toggled “3-D mode”, GPT-5 used this example to extrude hex cells into 3-D prisms.
4. UI Controls (Sliders & Real-time Updates)
https://github.com/dataarts/dat.gui
MIT-licensed micro-GUI library; GPT-5 bundles the minified source for the colony-size and resource-availability sliders.
https://leaverou.github.io/awesomplete/#advanced-examples
(Minor) Used for auto-completing nectar source names when users type in the “+Resource” field.
5. Color Scales & Data Visualization
https://github.com/d3/d3-scale-chromatic
Honey-level heat-map (interpolateYlOrRd) lifted directly from this repo.
https://coolors.co/palettes/trending
Palette “Bee-Gradient” (#FFC107 → #FF8F00 → #5D4037) scraped for the wax/honey visuals.
6. One-file Bundling Pattern
https://github.com/james2doyle/phaser-single-file
Shows how to embed CSS, JS and SVG data-URIs into a single .html; GPT-5 follows the same concatenation trick (notice the <style> block and base-64 SVG honey icons).
