DonutChart

What It Does

Shows part-to-whole composition in a compact circular chart.

Signature

db.DonutChart(data: 'List[Dict[str, str | float]]', value_key: 'str' = 'value', label_key: 'str' = 'label', title: 'Optional[str]' = None, height: 'int' = 300, loading: 'bool' = False, empty_message: 'str' = 'No chart data available', on_click: 'Optional[Callable[[Dict[str, Any]], None]]' = None) -> 'VNode'

Parameters

Name	Type	Default	Notes
data	List[Dict[str, str | float]]	required
value_key	str	'value'
label_key	str	'label'
title	Optional[str]	None
height	int	300
loading	bool	False
empty_message	str	'No chart data available'
on_click	Optional[Callable[[Dict[str, Any]], None]]	None

Example

import brickflowui as db

node = db.DonutChart(data=[{"label": "Healthy", "value": 42}], title="Command center", height="320px")

Integration Notes

• This component composes cleanly with layout primitives such as Card, Grid, Row, and Column.
• Prefer controlled state from Python when the value matters to your business logic or backend query layer.

Responsive Notes

Check the component inside a realistic layout, not only in isolation, so spacing, overflow, and action density stay comfortable on smaller screens.

Accessibility Notes

Pair this component with clear visible copy and predictable state changes so keyboard and assistive-technology users are not surprised.
