CirclifyItem class

Represents a single segment in a Circlify chart.

Each item has a value that determines its proportional size in the chart, a color for rendering, and an optional label displayed on the segment.

The id is used for animation diffing - items with the same id will animate smoothly when their values change.

Example:

CirclifyItem(
  id: 'sales',
  color: Colors.blue,
  value: 42.0,
  label: '42%',
)
