Chart/graph controls on form

Can anyone help me with my problem. I want to place some graphs/chart controls on my form. I want to place a treeview control on the left of my form as a navigation control and on the right I want to place some graph/chart controls that will show respective figures/position.
In the controls list, I can't find any genuine chart/graph control. Have they been moved to some other namespace different from 'System.Windows.Forms'.
