How to show balloon for an entity added.

Hello all,

I am new to Cesium and has some exposure to Google Earth. In google earth we can have a balloon that shows description related to the entity(http://www.google.com/earth/outreach/images/tutorials_annotate8.jpg). In Cesium do we also has any similar kind of feature. If yes then please share some example code for the same.

Thanks
Manoj

When you click on the states here it shows an infobox

It’s not directly over the entity though, maybe there’s a way to place the infobox above the entity instead of on the top-right.
