## What it is
VivaGraphJS is a JavaScript graph drawing library for rendering and visualizing graphs in the browser, supporting pluggable rendering engines (SVG and WebGL) and layout algorithms. Its underlying algorithms are provided by the ngraph module family.

## Use cases
- visualize a network graph in the browser
- render large graphs with WebGL
- draw force-directed graph layouts
- visualize social network friendships
- show related products as a graph
- customize node and link appearance in a graph visualization

## When to choose
- you need interactive graph rendering in a web page with SVG or WebGL output
- you want extensible, swappable layout algorithms and rendering engines
- you need to visualize large sparse graphs or networks in the browser

## When to avoid
- you need server-side or non-browser graph rendering
- you need a full-featured graph database or analytics engine rather than visualization
- you need actively developed features and frequent updates

## Facets
- artifact type: library
- maturity: maintenance
- function: data-visualization, graphics
- domain: data-visualization, web-development, graph-processing
- platform: browser
- tags: graph-drawing, webgl, svg, force-directed-layout, network-visualization, ngraph, nodejs, javascript
