A D3-based renderer for laying out and visualizing directed graphs in the browser.
dagre-d3 is a JavaScript library that renders directed graphs using D3.js, acting as a front-end to the Dagre layout engine. It solves the problem of creating automatically laid-out, interactive graph visualizations in web applications by combining Dagre's graph layout algorithms with D3's powerful SVG rendering capabilities.
Frontend developers and data visualization engineers who need to display complex directed graphs (like flowcharts, network diagrams, or dependency graphs) in web applications with interactive features.
Developers choose dagre-d3 because it seamlessly integrates the automatic layout precision of Dagre with the rich, customizable rendering and interactivity of D3, eliminating the need to manually position graph elements while maintaining full control over the visual output.

Open-Awesome is built by the community, for the community. Submit a project, suggest an awesome list, or help improve the catalog on GitHub.
Integrates Dagre to compute node positions and edge routing automatically, saving manual effort for directed graphs.
Uses D3.js for zooming, panning, and event handling, enabling rich, dynamic user interactions in SVG visualizations.
Allows extensive styling of nodes, edges, and labels through D3, giving developers complete control over the presentation.
Operates entirely in the browser, facilitating real-time updates and visualization without server-side processing.
Requires managing both Dagre and D3 libraries, increasing bundle size and setup complexity compared to all-in-one solutions.
Key documentation and examples are in a separate wiki, which can be hard to navigate and may lack comprehensive guides.
As a client-side tool, rendering very large graphs might lead to sluggish performance or browser memory issues.
Limited to directed graph layouts, not natively supporting undirected or other graph types without modifications.
