Functions

translateOptions

One vocabulary in, each engine's dialect out.

The adapters disagree about names for the same concept — dagre says rankdir, nodesep, ranksep; ELK says elk.direction with words instead of letters. Callers use one vocabulary whichever engine runs.

Exported for nested layout, which runs a DIFFERENT engine per container (group.subgraphLayout.algorithm), so it has to translate the one vocabulary per level rather than once up front. Reusing this is what stops the nested path from quietly forking the options schema.

ts
Copy
function translateOptions(
  engine: string,
  options: UnifiedLayoutOptions
): Partial<LayoutOptions>

treeLayout

Tree layout over one connected component.

Component packing (see component-packing.ts) is what turns this into a FOREST layout: each tree is laid out here, alone, and the boxes are packed afterwards. That division is why a five-tree forest comes out as five tidy trees rather than the pile dagre produces.

ts
Copy
function treeLayout(
  nodes: NodeModel[],
  links: LinkModel[],
  options: TreeLayoutOptions = {}
): LayoutResult
