Draw Dynamically circle inside Picture Box

You should be able to do this using the System.Drawing.Graphics.DrawEllipse method. The following MSDN article shows how you can draw a circle inside a square:

But what exactly do you mean by "Dynamically"?
If you mean you want to do this at runtime according to users actions, the details depend on the source image? And whether you want to keep the old circles or not?

Note that if you are looking for more advance drawing features, I am currently using Annotations features from Leadtools imaging programming SDK. I didn't use the System.Drawing.Graphics features because I want to draw the objects on a different layer over the image (the object will not be part of the image data).
