link.vertex(index)

Return the vertex at index.

link.vertex(index, vertex [, opt])

Update the vertex at index with value of vertex. By default the new value is merged into the old value. Pass the { rewrite: true } option along to disregard the old value.

A vertex has only two properties, x and y. It may be defined as a g.Point object.

Example vertex:

link.vertex(0, {
    x: 100,
    y: 200
});

Note that all vertices are stored in an array on the link model under the attribute vertices. Use the link.vertices function to access the array.
