Deprecated: Graphing a Vector Field in Space
This PG code shows how to make an interactive graph of a vector field displayed with the LiveGraphics3D Java applet. This example is deprecated because it uses Java, which is not universally supported by all web browsers.

To display the string of plot data
After you construct the vector field you like, don't forget to take a screen shot of it and make an image file such as
