Line class

Represents a line of data with associated attributes.

This class encapsulates a data object and optional attributes associated with that data. It provides methods to manipulate and manage the data and attributes.

Example usage:

// Creating a new Line instance
Line line = Line(data: 'Example data', attributes: {'color': 'red'});

// Setting new data and merging attributes
line.setData('Updated data');
line.mergeAttributes({'size': '12px'});

print(line.toString()); // Output: Data: Updated data, attributes: {color: red, size: 12px}
