Introduction

LiteGraph.js is a JavaScript library for creating node-based graphs with a visual editor, similar to Unreal Blueprints or Pure Data. This project focuses specifically on creating custom nodes with interactive controls (widgets), an essential aspect for building sophisticated node-based applications.

Key Features

This research covers:

1. Built-in widget types and their usage
2. Creating custom interactive controls
3. Handling mouse interactions for custom widgets
4. Data visualization within nodes
5. Event-based interactions between nodes
6. Best practices for node design and implementation

Examples Included

The repository includes several complete examples demonstrating different widget types and interaction patterns:

• Basic widgets (number, slider, combo, toggle, button)
• Custom interactive elements (buttons, knobs, graphs)
• Data visualization techniques
• Event handling and triggering

Getting Started

To use these examples in your own LiteGraph.js project:

1. Review the research-summary.md for an overview
2. Study the custom-nodes-guide.md for implementation details
3. Copy code from custom-widget-examples.js as needed
4. Uncomment the node registration lines to make them available in your graph editor
