Usage

CLI

Usage:
    svg-transit-map

Options:
    -y --invert-y Invert the Y axis

Examples:
    cat graph.json | svg-transit-map -y > map.svg

Where graph.json containts a graph object with three attributes:

{
    nodes: [ // list of all nodes
        {
            id: "900000042101", // required
            metadata: {
                x: 537.029, // x-coordinate in any metric, required
                y: 673.576 // y-coordinate in any metric, required, see also the --invert-y option
            }
        }
        // …
    ],
    edges: [ // list of all edges
        {
            // the direction of the edge will be ignored, source and target are therefore interchangeable
            source: "900000120025", // node id, required
            target: "900000120008", // node id, required
            metadata: {
                lines :["U5","U6"] // list of line ids, required. please note that parallel lines must be modeled as one edge with two metadata.lines entries
            }
        }
        // …
    ],
    lines: [ // additional information for lines. if lines are not found in this list, default colour / group will be applied
        {
            id: 'U6', // line id, required
            color: '#456', // line colour, optional
            group: 'U6' // line group id, optional. lines with the same group id will be merged info one for sections where they run in parallel
        }
        // …
    ]
}

As a library

The module can be used as a JS library, documentation for this will follow.

Example

For the U-Bahn Berlin graph in example/berlin.json and this command:

    cat example/berlin.json | svg-transit-map -y > example/berlin.svg

We get the following output

Berlin subway generated transit map
