Create a multi-curve visualization

This function creates a visualization with multiple curves, such as performance comparisons between different models.

Arguments

• x_values - X-axis values (common for all curves)
• y_values_list - List of Y-axis values, one for each curve
• series_names - Names for each curve
• title - Plot title
• x_label - X-axis label
• y_label - Y-axis label

Returns

• Box<dyn crate::visualization::MetricVisualizer> - A visualizer for the multi-curve plot
