Class Dataset

java.lang.Object
com.digitizer.core.Dataset
public class Dataset extends Object
Represents a dataset with a name, color and a mutable collection of Points.

Each dataset contains a user-visible name and a CSS hex color string. The color is cached as a Color for efficient rendering on the CanvasPanel. While datasets may be modified at runtime, callers should generally avoid changing internal lists directly unless intentionally editing the dataset state.
