draw a graph.
(1) read a Graph object
(2) read a Coords object
(3) read an IV object that contains a tag vector.
if (v,w) is an edge in the graph
and tags[v] == tags[w] then
draw edge (v,w)
(4) bbox[4] is the bounding box for the plot.
bbox = { xsw, ysw, xne, yne }
try bbox = { 0, 0, 500, 500 }
because coordinates are measured in points,
72 points per inch.
(5) rect[4] contains the frame for the plot.
to put a 20 point margin around the plot,
rect[0] = bbox[0] + 20
rect[1] = bbox[1] + 20
rect[2] = bbox[2] - 20
rect[3] = bbox[3] - 20
