strongly-connected-components

=============================

Given a directed graph, splits it into [strongly connected components](http://en.wikipedia.org/wiki/Strongly_connected_component).

## Example

```javascript

var scc = require("strongly-connected-components")

var adjacencyList = [

  [4], // 0

  [0,2], // 1

  [1,3], // 2

  [2], // 3

  [1], // 4

  [4,6], // 5

  [5,2], // 6

  [7,6,3], // 7

]

console.log(scc(adjacencyList))

```

## Install

    npm install strongly-connected-components

## API

### `require("strongly-connected-components")(adjacencyList)`

Computes the strongly connected components of a graph using Tarjan's algorithm.

* `adjacencyList` is an array of lists representing the directed edges of the graph

**Returns** An object containing:

* `components`: an array of arrays representing the partitioning of the vertices in the graph into connected components.

* `adjacencyList`: an array lists representing the directed edges of the directed acyclic graph between the strongly connected components
