Ngx-Graph and React: Compatibility, Alternatives, and a Working SVG Example

This static diagram illustrates the fixed-position React example below. It is not Ngx-Graph running in React or a benchmark screenshot.

Ngx-Graph is an Angular graph-visualization library, not a React component or a standalone JavaScript constructor. Installing its package in a React project does not provide a supported new NgxGraph() mounting API.

The official repository documents Angular components and module setup. A React ref, an SVG loader, or disabling server rendering does not supply that Angular runtime.

Choose an integration path

An iframe or an Angular custom-element wrapper may provide an application boundary, but neither is implemented by a new NgxGraph() call. Prove the boundary in a separate integration test before choosing that additional runtime.

A complete React example without Ngx-Graph

Save this as DependencyGraph.tsx in an existing React TypeScript project and render the exported component. No graph-library installation or webpack SVG-loader change is required.

const GRAPH_NODES = [
  { id: "input", label: "Input", x: 60, y: 80 },
  { id: "process", label: "Process", x: 180, y: 80 },
  { id: "output", label: "Output", x: 300, y: 80 },
]

const GRAPH_LINKS = [
  { id: "input-process", from: GRAPH_NODES[0], to: GRAPH_NODES[1] },
  { id: "process-output", from: GRAPH_NODES[1], to: GRAPH_NODES[2] },
]

const GRAPH_VIEWBOX = "0 0 360 160"
const NODE_RADIUS = 20
const LABEL_OFFSET = 35

/** Render a fixed-position diagram; layout and editing are outside this example. */
export default function DependencyGraph() {
  return (
    <svg viewBox={GRAPH_VIEWBOX} role="img" aria-label="Input connected to Process connected to Output">
      {GRAPH_LINKS.map((graphLink) => (
        <line key={graphLink.id} x1={graphLink.from.x} y1={graphLink.from.y}
          x2={graphLink.to.x} y2={graphLink.to.y} stroke="currentColor" />
      ))}
      {GRAPH_NODES.map((graphNode) => (
        <g key={graphNode.id}>
          <circle cx={graphNode.x} cy={graphNode.y} r={NODE_RADIUS}
            fill="white" stroke="currentColor" />
          <text x={graphNode.x} y={graphNode.y + LABEL_OFFSET} textAnchor="middle">
            {graphNode.label}
          </text>
        </g>
      ))}
    </svg>
  )
}

Expected result: three labeled circles and two connecting lines. Changing a node's coordinates changes both its position and the links that reference it.

This is a fixed-position illustration. It does not implement automatic layout, dragging, zooming, selection, or keyboard node editing. The SVG has an accessible name; an application with interactive graph controls needs additional keyboard and focus behavior.

When a library is the better choice

For editable flows, evaluate React Flow's React examples. For a layout algorithm with custom rendering, evaluate D3 separately from the React component that draws its output.

Compare features using the same graph, browser, and interactions. Record layout time, interaction latency, and memory use. Node count alone does not establish that one library is faster than another; this guide makes no universal 500-node or 1,000-node performance claim.

Troubleshooting the original integration approach

• An Angular peer dependency is missing: follow the package's Angular requirements or choose a React implementation; a TypeScript cast cannot provide a runtime.
• An export or constructor cannot be found: check the package's documented exports instead of inventing an adapter around an unsupported API.
• A Next.js server-rendering error appears: identify the actual browser-only dependency. Turning off server rendering does not convert an Angular component into a React component.
• A small graph is slow: profile layout and rendering separately before introducing virtualization or workers.

For ordinary tabular source information, the React editable-table guide covers a different presentation task. Use a graph when relationships are the information the reader needs to inspect.
