react-dag-editor

React component to create graphic user interface with: – draggable nodes with ports and edges on a directed graph editor. – extensibility to customize the widgets or behaviors. – accessbility and testability support

Overview

React component to create graphic user interface with:

  • draggable nodes with ports and edges on a directed graph editor.
  • extensibility to customize the widgets or behaviors.
  • accessbility and testability support

About the name “react-dag-editor”

  • react: it is a react component created from scratch.
  • dag: directed acyclic graph editor. Our a11y solution assumes the graph is a DAG. If you intend to turn off the a11y features, it is fine to draw undirected or cyclic graph with this component.
  • editor: it supports readonly graphic data visualization. However the reason you choose this library is the highlight in the user interaction to create/edit a graph.
