Add tooltip to 2graph vis.js library

I am using the 2d line graph of vis.js ( http://visjs.org/graph2d_examples.html ). Is there a way to add a tooltip to data points so that when you hover or click you see the value in a popup window or somewhere else?

This is the feature they plan to add. The closest thing I see is a comment on trying to solve the problem on my own:

This solution is rather simpe:

Add a label to points, for example.

var point = {
    x: ...,
    y: ...,
    label: {
        content: POINT_LABEL
    }
};

points.push(point);

var dataset = new vis.DataSet(points);
