An easy way, although may be not very fast if the graphic is huge, is to
load the graphic into a Image Box within the PictureBox. As long as you set
the strech property of the ImageBox to true, changing the size of the
ImageBox will act as a zoom, and changing the position of the ImageBox
within the pictureBox will allow you to show any part of the graphic if it
is too big for the PictureBox.

Another way is to use the PaintPicture Method. Is pretty similar to use some
API calls like StrechBlt and BitBlt but I think could be a better option
when working with PictureBoxes.
