Graph Chart

The Graph Chart component in Lowcoder is designed for mapping networks, connections, and relationships between entities. Unlike bar or line charts that focus on metrics, the Graph Chart reveals how nodes (things) are linked through edges (connections) — perfect for illustrating complex systems.

Ideal Use Cases

• Organisational charts

• Social networks (users and their followers/friends)

• IT infrastructure maps (servers, APIs, databases)

• Dependency graphs (tasks, modules, or processes)

Data Structure

Graph Charts work with two key datasets: nodes and links.

{
  "nodes": [
    { "id": "A", "label": "Start" },
    { "id": "B", "label": "Process" },
    { "id": "C", "label": "End" }
  ],
  "links": [
    { "source": "A", "target": "B" },
    { "source": "B", "target": "C" }
  ]
}

Core Features

• Chart Type: Drag “Graph Chart” component from the right window of the Editor page

• Force Layout: Automatically organizes nodes based on physical forces (repulsion, gravity, etc.)

• Interactive: Nodes can be draggable; tooltips and hover effects are supported

• Directional Arrows: Show flow or influence (optional via edge styling)

Customisation & Styling

• Customize node size, color, and labels

• Use ECharts JSON config for full control over:

  • Edge curvature or thickness

  • Node grouping or clustering

  • Tooltip formatting

  • Animation effects
