I'm trying to implement data to this codepen link website.

I really love the design but cannot figure out how to add data points inside. Data points are supposed to be clickable, pretty much a button scenario.

if you check the link and the code inside, I think it has to be added somewhere between these lines

var linesToDraw = [];
        for(var i = 0; i < points.length; i++){
            linesToDraw.push({
                control: controlPoint,
                p1: points[i],
                func: self.drawLine
            });
        }
