s and parallel edges are ignored by this function. Note 
that the restriction that the graph be maximal planar does not
mean that this function can only draw maximal planar graphs (the graph pictured
above is not maximal planar, for example). If you want to 
draw a graph <i>g</i>, you can create a copy <i>g'</i> of <i>g</i>, store a 
mapping <i>m</i> of vertices in <i>g'</i> to vertices in <i>g</i>, 
<a href="make_maximal_planar.html">triangulate</a> <i>g'</i>, and then send 
<i>g'</i> in as the input to <t
