ngx-charts-dag

October 05, 2017
A Directed Acyclic Graph (DAG) visualization for angular - implemented using ngx-charts.
Note: ngx-charts-dag 2.0.0 works only with Angular 4.x. To use ngx-charts-dag with Angular 2.x, use ngx-charts-dag 1.x.

Demo

https://swimlane.github.io/ngx-charts-dag/

Features

  • Custom templates for nodes and edges
  • Automatic layout using Dagre
  • Animations

How is it different than the ngx-charts-force-directed-graph component which is distributed with ngx-charts?

This visualization uses the Dagre layout, which is specialized for directed graphs, where as ngx-charts-force-directed-graph uses D3's force directed layout.

ngx-charts-dag is better suited for visualizing flow diagrams which have a clear start and end.

Installation

  1. npm install @swimlane/ngx-charts-dag --save
  2. Make sure the peer dependencies are installed (d3)
  3. Import NgxChartsDagModule into your module
  4. Use the ngx-charts-directed-graph component in your components
