Draw a simple undirected graph G!?!

Draw a simple undirected graph G using paint program that has 12 vertices, 18 edges, and 3 connected components. Why would it be impossible to draw G with 3 connected components if G had 66 edges?

Can someone show me how this is done? It will help me with my final preparation.
Someone please help me with this.
This isn't a programming question and it's rather esoteric so no one may have an answer for you.

Have you tried doing a search for "Euler tTour"???:
