ldraw

PURPOSE

ldraw(g,line_style) --- draw a graph with vertices marked with their labels

SYNOPSIS

function ldraw(g,line_style)

DESCRIPTION

 ldraw(g,line_style) --- draw a graph with vertices marked with their labels
 If the graph is unlabled, we use the vertex numbers instead.
 See also draw, cdraw, and ndraw.

CROSS-REFERENCE INFORMATION

This function calls:

• draw draw(g) --- draw g in a figure window
• draw_labels draw_labels(g) --- add labels to a drawing of g
• is_labeled is_labeled(g) --- determine if there are labels on vertices.
• ndraw ndraw(g) --- draw g in a figure window with numbered vertices

This function is called by:
