10.3: Image created coarsely gridded data

This example reads gridded ascii station data (`Read Data'), creates an interpolated image (`convert grid ...'), and then plots the image.

There are some other useful tricks in this example, such as calling `awk' and `wc' from the unix system.

(In the plot shown, all `query' questions were answered with carriage return, yielding the defaults; the `-p' flag was specified on execution, so the time stamp was not drawn.)
