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" }
  ]
}
