ONNX Codebase Explorer

🌐 Live Demo | 📖 Deployment Guide

A visual, interactive website for understanding the ONNX (Open Neural Network Exchange) codebase. This tool helps developers explore ONNX's architecture from a high level down to detailed implementation specifics.

Note: This is a standalone documentation website, separate from the main ONNX repository. It analyzes and visualizes the ONNX codebase structure without modifying the original source code.

🎯 What This Website Does

The ONNX Codebase Explorer provides:

1. Top-Down Navigation - Start with high-level concepts and drill down to code details
2. Interactive Architecture Maps - Visual representation of the codebase structure
3. Module Documentation - Detailed information about each ONNX component
4. Code Flow Diagrams - Understanding how different parts connect
5. Searchable Documentation - Find specific functions, classes, or concepts quickly

🏗️ Architecture

Multi-Level Exploration

The website uses a zoom-level approach to understanding:

• Level 1: 🌍 High Level - What is ONNX, core concepts, ecosystem overview
• Level 2: 🏗️ Architecture - Repository structure, main modules, relationships
• Level 3: 🔧 Modules - Detailed module exploration, APIs, classes
• Level 4: 📝 Code - Implementation details, algorithms, code patterns

Navigation Structure

Data Structure

The codebase information is stored in JavaScript objects:

const onnxCodebase = {
    overview: { /* High-level stats and info */ },
    architecture: { /* Repository structure */ },
    modules: { /* Detailed module information */ },
    protocolBuffers: { /* Protocol buffer files */ }
};

📱 Responsive Design

The website adapts to different screen sizes:

• Desktop (>1024px) - Full sidebar, multi-column layouts
• Tablet (768-1024px) - Collapsible sidebar, adjusted grids
• Mobile (<768px) - Stacked layout, touch-friendly navigation
