## What it is
A TypeScript-first JavaScript library providing layered layout algorithms for visualizing directed acyclic graphs (DAGs). It offers a dagre-compatible API plus advanced algorithms like optimal edge crossing minimization, Zherebko, and Grid layouts, and works as a drop-in layout engine for React Flow.

## Use cases
- layout directed acyclic graphs for visualization in the browser
- replace dagre as the layout engine in React Flow
- compute layered sugiyama layouts with minimal edge crossings
- render dependency trees or pipelines with d3
- auto-position nodes in a flowchart or workflow diagram

## When to choose
- you need DAG layout in JavaScript/TypeScript with a small bundle size
- you want better layouts than dagre, such as optimal decrossing or Zherebko/Grid algorithms
- you use React Flow and want a drop-in dagre replacement
- you value full TypeScript type safety in a graph layout library

## When to avoid
- you need layouts for cyclic graphs rather than DAGs
- you need compound/clustered graph layout or very large general graph layouts where elkjs is more capable
- you need a non-JavaScript environment
