This tool generates data in the JSON Graph Format. Note that instead of storing all nodes and edges in one JSON file, it will create nodes.ndjson and edges.ndjson. These are ndjson-encoded lists of all nodes and edges, respectively.

A node from nodes.ndjson looks like this:

{
	"id": "8013487",
	"label": "Oranienburg",
	"metadata": {
		"latitude": 52.754697,
		"longitude": 13.249084
	}
}

An edge from edges.ndjson looks like this:

{
	"source": "8081722",
	"target": "8013487",
	"relation": "suburban",
	"metadata": {
		"line": "S 1",
		"time": 180000
	}
}
