pict-provider-graphlayout

Pure, DOM-free node-placement algorithms and edge-routing themes for graph canvases. Extracted from pict-section-flow so the layout and routing logic is reusable and testable on its own.

What is here

• Layouts - node-placement algorithm descriptors { Name, Label, Apply, DefaultParameters, ParameterSchema }: Custom, Layered, Staggered, ForcedFromCenter, Grid, Circular, Tabular, Columnar, plus the Coerce and Rank helpers they build on.
• Edges - edge-routing theme descriptors { Name, GeneratePath, ... }: Bezier, Orthogonal, Straight, OrthogonalSnap, Perimeter, PerimeterLinear, PerimeterOrthogonal, plus the PerimeterMath helper.

Usage

const libGraphLayout = require('pict-provider-graphlayout');

const tmpGrid = libGraphLayout.Layouts.Grid;       // a layout descriptor
const tmpBezier = libGraphLayout.Edges.Bezier;     // an edge-theme descriptor

pict-section-flow's Layout service registers these through its registerAlgorithm / registerEdgeTheme API. Any host that wants the same algorithms without the flow view can register them the same way.

Status

Extracted in Phase 1b of the pict-section-flow 2.0 plan. The path-generation math (bezier and orthogonal routing) joins here next as a geometry-injected core, at which point this module depends on pict-provider-graphgeometry.
