## What it is
El Grapho is a high-performance WebGL graph data visualization engine for the browser that can render millions of interactive nodes and edges. It supports layouts like force-directed graphs, trees, radial trees, clusters, and chords via a simple JavaScript API.

## Use cases
- visualize large network graphs in the browser
- render force-directed graphs with millions of nodes
- display interactive tree and radial tree diagrams
- build cluster or chord diagrams for web dashboards
- explore graph datasets interactively with zoom and pan

## When to choose
- you need to visualize very large graphs where performance matters
- you want a lightweight browser-based graph rendering engine
- you need multiple graph layouts (tree, force, cluster, chord) in one library

## When to avoid
- you need server-side or non-browser rendering
- you need rich built-in analytics or graph algorithms rather than visualization
- you need actively maintained software with recent updates and support

## Facets
