Arc diagram in Angular

Lay every node on one line and join related pairs with an arc, so the links read at a glance

type: 'arc', source, target, value

This lays every node on one line and joins related pairs with an arc above it. It makes the connections in a set of items read at a glance, so clusters and hubs stand out along a single axis.

Building…

Loading a live grid…

This is the Angular version. A standalone component takes the whole configuration through one config input, surfaces grid events as outputs, and exposes the live grid on a getter for anything the inputs do not cover.

The configuration

import { Component, ViewChild, AfterViewInit } from '@angular/core';
import { bootstrapApplication } from '@angular/platform-browser';
import { createGrid } from '@toclocoinc/lattice-grid';
import '@toclocoinc/lattice-grid/css';
import { createChart } from '@toclocoinc/lattice-grid/modules/charts';
import '@toclocoinc/lattice-grid/modules/chart-arc';  // opt in to the arc type
import { LatticeGridComponent, provideLattice } from '@toclocoinc/lattice-grid/angular';

@Component({
  selector: 'app-root',
  standalone: true,
  imports: [LatticeGridComponent],
  template:
    '<div id="chart" style="height:320px"></div>' +
    '<lattice-grid [config]="grid" style="display:block;height:320px;margin-top:14px"></lattice-grid>',
})
export class AppComponent implements AfterViewInit {
  @ViewChild(LatticeGridComponent) gridRef!: LatticeGridComponent;

  grid = {
    rowKey: 'id',
    columns: [
      { field: 'source', title: 'From', filter: { type: 'set' } },
      { field: 'target', title: 'Calls', filter: { type: 'set' } },
      { field: 'calls', title: 'Calls / min', type: 'number', total: 'sum' },
    ],
    rows: [/* one edge a row: source, target, calls */],
  };

  ngAfterViewInit() {
    createChart({ grid: this.gridRef.grid, container: '#chart', type: 'arc', source: 'source', target: 'target', value: 'calls', title: 'Which service calls which' });
  }
}

bootstrapApplication(AppComponent, {
  providers: [provideLattice({ createGrid })],
});
