This is building Swimlane flowchart based on ReactFlow and Dagre alogrithm. It contains below features:
- auto layout based on DAG Dagre algorithm.
- auto change edge path if there is intermediate node.
- supports change layout
Top to BottomandLeft to Right
- v0.1.1 Support Swimlane crosses multiple layers if nodes within same swimlane communicate each other.
