Suburst Chart

🌞 Sunburst Chart – Radial Insight Into Hierarchies

The Sunburst Chart in Lowcoder presents hierarchical data in a circular, multi-level format, allowing users to explore nested relationships with a quick glance. Think of it as a pie chart that goes deeper — each level of the hierarchy adds a new ring, radiating from the center outward.

🌐 Best Used For:

• Organization structures (e.g., Company → Departments → Teams)

• Product category breakdowns

• File directory visualizations

• Multi-tiered survey results or user segments

🧩 Example Data Structure

Sunburst data is typically hierarchical and tree-like:

{
  "name": "Company",
  "children": [
    {
      "name": "Engineering",
      "children": [
        { "name": "Frontend", "value": 10 },
        { "name": "Backend", "value": 15 }
      ]
    },
    {
      "name": "Marketing",
      "value": 20
    }
  ]
}

Each node can have a value, and/or children for deeper nesting.

⚙️ Key Features

• Chart Type: Drag “Sunburst” from the components section onto Editor's View

• Nested Levels: Automatically expands based on data depth

• Segment Size: Proportional to values — larger value, wider arc

• Tooltips: Hover to view node details (name, value, path)

🎨 Customisation & Theming

• Define color schemes by level or branch

• Style labels (e.g., rotate, hide, or show on hover)

• Control level radius, animation, and visual emphasis using ECharts JSON configuration
