# rebalanceSubgraphs

[Source](https://github.com/konoe-akitoshi/shumoku/blob/main/libs/@shumoku/core/src/layout/interaction.ts#L227)

Rebalance the entire layout after any mutation. Uniform algorithm: 1. Recompute subgraph bounds (bottom-up, deepest first) 2. Resolve subgraph vs subgraph sibling collisions 3. Resolve subgraph vs free node collisions (push nodes away)

```
rebalanceSubgraphs(nodes: Map<string, Node>, subgraphs: Map<string, Subgraph>, ports: Map<string, ResolvedPort>, opts?: { direction?: "TB" | "BT" | "LR" | "RL"; subgraphLabelHeight?: number; subgraphPadding?: number }): void
```

## Parameters

| Parameter | Type | Description | Default |
| --- | --- | --- | --- |
| `nodes` | `Map<string, Node>` | No additional description. | `—` |
| `subgraphs` | `Map<string, Subgraph>` | No additional description. | `—` |
| `ports` | `Map<string, ResolvedPort>` | No additional description. | `—` |
| `opts` | `{ direction?: "TB" | "BT" | "LR" | "RL"; subgraphLabelHeight?: number; subgraphPadding?: number }` | No additional description. | `{}` |

## Returns

```
