.SH SYNOPSIS
.B grap
[ files ]
.SH DESCRIPTION
.I Grap
is a
.IR pic (1)
preprocessor for drawing graphs on a typesetter.
Graphs are surrounded by the
.I troff
`commands'
.B \&.G1
and
.BR  \&.G2 .
Data that is enclosed is scaled and plotted,
with tick marks supplied automatically.
Commands exist to modify the frame,
add labels, override the default ticks,
change the plotting style,
define coordinate ranges and transformations,
and include data from files.
In addition, 
.I grap
provides the same loops, conditionals and macro processing that
.I pic
does.
