Directed Graph Component for Angular

This is a modular component to render an SVG graph of nodes connected by edges.

By default, each node is rendered as a box, with curved lines connecting them.

This can be customized by providing your own templates to render the node and edges.

Data is expected to be supplied to the graph as basic Node and Edge objects (see model.ts). These interfaces may be optionally parameterized to wrap custom data specific to you graph. Node and Edge objects are passed to the custom templates so you may access your custom data in your templates.

Example usage

Create a simple graph using the default rendering options:

@Component({
  template: `<directed-graph [graph]="myGraphData"></directed-graph>`,
  ...
})
export class MyGraph {
  node1 = {id: 'Node 1', width: 100, height: 50};
  node2 = {id: 'Node 2', width: 100, height: 50};
  edge1 = {src: this.node1, dest: this.node2, points: []};
  myGraphData = {
    nodes: [this.node1, this.node2],
    edges: [this.edge1],
  };
}
