## What it is
Dagre is a JavaScript library for laying out directed graphs on the client side, computing node and edge positions automatically. The dagre-d3 companion package provides a D3-based renderer for visualizing those layouts in the browser.

## Use cases
- automatically layout directed graphs in the browser
- render flowcharts and dependency diagrams with D3
- compute node positions for graph visualizations
- draw DAG diagrams in a web app
- visualize state machines or workflow graphs client-side

## When to choose
- you need automatic layout of directed graphs in JavaScript
- you want a D3-based renderer for graph diagrams
- you need client-side layout without a server

## When to avoid
- you need interactive graph editing rather than static layout
- you need force-directed or undirected graph layouts
- you need server-side or non-JavaScript graph layout

## Facets
- artifact type: library

- function: data-visualization, graphics
- domain: data-visualization, web-development, frontend
- platform: browser
- tags: graph-layout, directed-graphs, d3, dagre-d3, client-side, nodejs, javascript
