## Installing

```shell

npm install -g generate-db-graph

# or with ad-hoc install

npx generate-db-graph 

```

## Usage

```

Usage:

    generate-db-graph 

Examples:

    generate-db-graph 8011102 # start at Berlin Gesundbrunnen

```

This tool generates data in the [JSON Graph Format](https://github.com/jsongraph/json-graph-specification/blob/master/README.rst#json-graph-specification). Note that instead of storing all nodes and edges in one JSON file, **it will create `nodes.ndjson` and `edges.ndjson`. These are [ndjson](http://ndjson.org)-encoded lists of all nodes and edges**, respectively.

A node from `nodes.ndjson` looks like this:

```json

{

	"id": "8013487",

	"label": "Oranienburg",

	"metadata": {

		"latitude": 52.754697,

		"longitude": 13.249084

	}

}

```

An edge from `edges.ndjson` looks like this:

```json

{

	"source": "8081722",

	"target": "8013487",

	"relation": "suburban",

	"metadata": {

		"line": "S 1",

		"time": 180000

	}

}

```
