placeNode
APIの説明は英語のcanonical sourceを表示しています。
**Geometric** placement for a single unpositioned node: find the point nearest `initial` that doesn't overlap any existing node or subgraph. The graph's link structure is deliberately ignored — this is the primitive for "drop the node exactly where the user clicked", "paste at cursor", "convert BOM item to diagram node at the canvas edge", i.e. user-driven placement where the surrounding topology should not influence the outcome. For **structural** placement (re-layout based on link flow, pin a set of nodes, arrange a selection), use `layoutNetwork` with its `fixed` / `hints` options instead. The two APIs stay separate because their intents differ: `placeNode` is O(existing obstacles) geometry, `layoutNetwork` is a full Sugiyama run.
