BubbleDataPoint class

Represents a bubble data point with size information.

Extends ChartDataPoint with an additional size property for bubble charts. The size represents the third dimension of data visualization, allowing you to encode three variables (x, y, size) in a single chart.

Example

const BubbleDataPoint(
  x: 10,
  y: 20,
  size: 50,
  label: 'Product A',
)

• ChartDataPoint for standard two-dimensional points
• BubbleDataSet for collections of bubble data points (import from models)
