Enhance ChartData and LineChartDataset functionality

Updated the `ChartData` class to include `Datasets` and `Labels` properties with appropriate attributes for JSON handling.

Significant modifications to the `LineChartDataset` class include the addition of various properties for visual customization, hover effects, and point styling. New properties such as `ShowLine`, `SpanGaps`, `Stepped`, `Tension`, `XAxisID`, and `YAxisID` have been introduced to improve line rendering and dataset management.

Overall, these changes enhance the functionality and customization options of the charting library.
