converter

Base converter class for lineage graph exports.

GraphConverter

Bases: ABC

Abstract base converter for lineage graph export.

Converters transform LineageGraph (format-agnostic data model) into specific export formats (Mermaid, Neo4j, GraphML, etc.).

All conversion is synchronous - operates on pre-loaded graph data.

convert abstractmethod

convert(graph: LineageGraph, **options) -> Any

Convert graph to target format.

Parameters:

Name	Type	Description	Default
graph	LineageGraph	LineageGraph with pre-loaded nodes and edges	required
**options		Format-specific conversion options	{}

Returns:

Type	Description
Any	Format-specific output (MermaidDiagram, Cypher queries, etc.)
