Javascript Pop Up Window

How do you make a Javascript Pop Up Window much like the one on http://www.datadrain.com?

Just have a look at the source code:

function data() {
window.open('URL','NAME_OF_THE_WINDOW','toolbar=no,location= no,directories=no,status=no,menubar=no,scrollbars=no,resize= no,width=778,height=400')
}

(play a bit with the size and the different commands...)

Make a link to "javascript:data()" and your window will pop up when someony clicks the link.
