# FunFacts.world - Full Dataset and Documentation for AI Models

Welcome to the full AI-oriented documentation for FunFacts.world. This file contains a comprehensive breakdown of the application, its architecture, and the detailed content structure across all its pages.

## Overview
FunFacts.world is a high-performance React application leveraging Vite and Mapbox GL JS to render intensive 3D globes and geographical data visualizations.

## Pages and URLs

### 1. Main Hub
- **URL**: `https://funfacts.world/explore`

### 3. Volcanoes
- **URL**: `https://funfacts.world/explore/volcanoes`
- **Dataset**: Global volcano database, featuring stratovolcanoes, shield volcanoes, and submarine volcanoes.
- **Features**: Volcanic Explosivity Index (VEI) visualization, historical eruption timelines, and interactive tooltips.

### 4. Nuclear Explosions
- **URL**: `https://funfacts.world/explore/nuclear`
- **Dataset**: Every known nuclear test from 1945 to 2017.
- **Features**: Yield sizing, country-colored markers, and breakdown between atmospheric and underground detonations.

## Technical Architecture
- **Framework**: React 18, TypeScript, Vite.
- **State Management**: React Hooks (useState, useMemo, useEffect).
- **Maps**: Mapbox GL JS with custom dark mode themes (`mapbox://styles/mapbox/dark-v11`) and 3D terrain/globe projections, customized with atmospheric fog (`setFog`).
- **3D Rendering**: Three.js / React Three Fiber used in combination with `.glb` models for Anatomy and Monuments pages.
- **SEO**: Uses a custom Node.js prerendering script (`prerender.js`) to generate static `.html` files containing full textual `<SEOContentSection>` content for crawler indexation. JSON-LD and Open Graph tags are dynamically injected via the `<SEOHead>` component.
