0.1.0 #
- Initial release.
- Ports:
ElkPort.side/ElkPortSide; edges may reference port ids and attach at computed border points (ElkPositionedNode.ports). - elkjs JSON ingestion:
ElkGraph.fromJson(andfromJsonon nodes/edges/ ports/labels) parse the elkjs graph JSON shape. - Validation harness (
tool/validation/) comparing structural agreement against real elkjs. - ELK-style layered layout: cycle breaking, network-simplex layering, crossing minimization, Brandes–Köpf coordinate assignment.
- Orthogonal edge routing with computed bend points and parallel-edge lanes.
- Compound graphs / clusters with parent-relative result coordinates.
- ELK spacing model (
spacing.baseValue), model order constraints, and Brandes–Köpf fixed-alignment options. - elkjs-style graph API (
ElkGraph/ElkNode/ElkEdge→ElkResult).
