The data is retrieved and stored in a list (of ActorMovieIMDB objects).
Iterate through the list and add vertices for actors and movies. Note: onlyadd the nodes if they are not already in the graph.
Compile, run, and visualize and you should see a large graph
Style the graph. Look for the two actors 'Cate_Blanchett' and 'Kevin_Bacon_(I)'; for these actors, set their node colors to something unique and their linkes to the movies a different color (refer to the graph tutorial for how to change visual attributes)
