Test of Curve Direction

Although simple CLDs can use a single default direction for the edges, for some complex CLDs we need to be able to control the direction of the edges. Vis.js allows us to do this using the edge curve parameter:

Here are two edges. The default edge is curvedCW for clockwise. In the second edge is curvedCCW for counter clockwise.

        "target": "population",

        "curve": {
            "type": "curvedCW"
        },

        "curve": {
            "type": "curvedCCW"

    }
