Graphlib is a JavaScript/TypeScript library providing data structures for directed and undirected multi-graphs along with common graph algorithms. It is the graph data-structure library underlying the Dagre diagram-layout project.

Use cases

• model directed and undirected graphs in JavaScript
• build a dependency graph of tasks or modules
• run graph algorithms like shortest path or topological sort
• represent a multigraph with parallel edges
• serialize and deserialize graph structures as JSON
• back a flowchart or DAG layout tool with graph data

When to choose

• you need a lightweight, dependency-free graph data structure in JS/TS
• you are building on top of Dagre or need compatibility with its ecosystem
• you want basic graph algorithms without pulling in a heavy library like graphology or Cytoscape

When to avoid

• you need advanced graph algorithms, centrality measures, or community detection
• you need graph visualization or rendering (use Cytoscape.js or D3 instead)
• you need high-performance graph processing on very large graphs
