        !            18: .Nm Graph
        !            19: with no options takes pairs of numbers from the
        !            20: standard input as abscissas and
        !            21: ordinates of a graph.
        !            22: Successive points are connected by straight lines.
        !            23: The graph is encoded on the standard output
        !            24: for display by the
        !            25: .Xr plot 1

        !            27: .Pp
        !            28: If the coordinates of a point are followed by
        !            29: a nonnumeric string, that string is printed as a
        !            30: label beginning on the point.
        !            31: Labels may be surrounded with quotes "...", in
        !            32: which case they may be empty or contain blanks
        !            33: and numbers;
        !            34: labels never contain newlines.
        !            35: .Pp
        !            36: The following options are recognized,

        !            40: Supply abscissas automatically (they are missing from

        !            42: argument (default 1).
        !            43: A second optional argument is the starting point for
        !            44: automatic abscissas (default 0 or lower limit given by

        !            58: of connecting lines:
        !            59: 0 disconnected, 1 connected (default).
        !            60: Some devices give distinguishable line styles
        !            61: for other small integers.
        !            62: .Tp Fl s
