{info}
While almost any kind of plotting feature can be created using the above features in combination with the Tcl programming language, most users will eventually expect a higher level interface; this task is currently being worked on.
The three steps goes like this
# Open a Postscript file
# Draw something, e.g. a map and some axes
# Close the postscript file
