Overview

Sunburst Chart widget is a type of visualization that shows hierarchy through a series of rings, that are sliced for each category node. Each ring corresponds to a level in the hierarchy, with the central circle representing the root node and the hierarchy moving outwards from it.

Here is the dataset that defines the above chart configuration:

{
    "id": "X0",
    "name": "Total",
    "children": [
        {
            "id": "admin",
            "name": "Administrative",
            "value": 101,
            "children": []
        },
        {
            "id": "Other",
            "name": "Other",
            "value": 127
        },
        {
            "id": "primary",
            "name": "Primary",
            "value": 11
        },
        {
            "id": "minor",
            "name": "Secondary",
            "value": 99
        }
    ]
}

Each segment of the chart can have the following attributes:

Attribute	Description
value	Required. The numerical value of the segment.
name	The name of the segment.
color	The Hex color code for the segment.
children	The array of segment objects. Optional.

The value of the segment is calculated automatically as a sum of all the segment values of its children. If colors are not specified in the data, the default colors will be applied. Names will appear on the legend and on the tooltip of each segment.
