All Known Implementing Classes:
DefaultDataConverter
public interface DataConverter extends Serializable
Converts tabular data into chart Series for rendering. The input is a list of rows, where each row is a column-name-to-value map.

Implementations may return one or more series depending on the data. The DefaultDataConverter provides automatic chart type detection based on column names and supports multi-series grouping via a series column. Custom implementations can apply any conversion logic appropriate for their use case.
