TLineAreaChart class

A customizable line area chart widget.

This widget displays multiple series of data in a line area chart format. It supports legends, tooltip behavior, and an options button.

The chart uses SfCartesianChart from Syncfusion for rendering.

Example usage:

TLineAreaChart(
  title: "Sales Performance",
  data: [
    [LineChartData(x: "Jan", y: 50, color: Colors.blue)],
    [LineChartData(x: "Feb", y: 80, color: Colors.green)],
  ],
  legendLabels: [LegendLabel(label: "Sales", color: Colors.blue)],
  showLegends: true,
  showOption: true,
  optionTap: () => print("Options tapped"),
)
