## What it is
Zeu.js is a JavaScript library offering a collection of prebuilt canvas-based visualization components such as meters, clocks, and network graphs. It is designed for building real-time TV dashboards, monitoring UIs, and IoT web interfaces.

## Use cases
- build a real-time TV dashboard for a command center
- create a monitoring UI with animated meters and gauges
- display IoT sensor data in a web interface
- render a network graph of live connections
- show a digital clock and heartbeat status on a status wall
- visualize message queue throughput in a browser

## When to choose
- you need prebuilt, animated canvas components for dashboards without heavy charting frameworks
- you are building a TV wall or command center display with real-time updates
- you want a lightweight, dependency-free visualization library for IoT or monitoring UIs

## When to avoid
- you need standard business charts like bar, line, or pie charts with axes and legends
- you require server-side rendering or a framework-specific component system like React bindings
- you need a library with active development and recent releases, as the last release was in 2018
