Answer 1

The small ones (#3) must be using Sparkline: http://omnipotent.net/jquery.sparkline/

I'm not sure about #2, but you can get the same result using flot: http://code.google.com/p/flot/

Answer 2

marcgg might be right. You should also consider using a svg library to draw vector graphs, though. Have a look at Raphaël / gRaphaël.

Even though Raphaël is my favorite library, there are several others.
