1 2# Drawing a simple graph 3 4Previous examples dealt with charting and plotting, but now we 5transition into examples on graph drawing (with vertices and 6edges). Thus we begin using the `PlotGraph` function. 7 8It can take a vertex set and relation, as shown below. 9 10``` 11G := Group( (1,2,3), (1,2) );; 12S := function ( H, G ) return IsSubgroup( G, H ); end;; 13PlotGraph( AllSubgroups( G ), S ); 14``` 15 16As you can see below, this doesn't look as nice as we'd like, so 17let's consider how to improve it in the next example. 18 19
