### The underlying JavaScript code

```
JXG.Options.point.zoom = true;
var brd = JXG.JSXGraph.initBoard('jxgbox', {boundingbox:[-0.1,1.1,1.1,-0.1]});
var i, h, s, v;
for (i=0;i<30;i++) {
h = Math.random()*360;
s = Math.random();
v = 1.0;
brd.createElement('point',[Math.random(),Math.random()],
{
withLabel:false,
face:'circle',
size:Math.random()*65,
strokeColor:JXG.hsv2rgb(h,s,v),
fillColor:JXG.hsv2rgb((h+180)%360,s,v),
highlightFillColor:JXG.hsv2rgb(h,s,v),
fillOpacity:0.7,
highlightFillOpacity:0.4
});
}
```
