## What it is
Meta2d.js is a TypeScript 2D engine for real-time data exchange and interactive canvas-based graphics on the web. It is designed for building Web SCADA systems, IoT dashboards, and digital twin visualizations.

## Use cases
- build a web scada dashboard
- visualize real-time iot sensor data
- create digital twin 2d visualizations
- make an interactive diagram editor
- render animated industrial monitoring screens
- draw data-driven canvas graphics in the browser

## When to choose
- you need real-time data-driven 2D graphics for SCADA, IoT, or digital twin scenarios
- you want interactive events, animations, and message subscription in a canvas engine
- you prefer a MIT-licensed TypeScript library with an online editor

## When to avoid
- you need 3D rendering rather than 2D
- you want a general-purpose charting library for standard business charts
- you need a non-web platform like native mobile or desktop

## Facets
- artifact type: library
- maturity: active
- function: data-visualization, graphics, animation, ui-components
- domain: web-development, frontend, iot, data-visualization, simulation
- platform: browser
- tags: 2d-engine, canvas, scada, digital-twin, diagram-editor, real-time-data, iot-dashboards, web-server, typescript, nodejs
