Hello,  
  


I am new to mathematics and computer science. I would like to learn graphs and graph theory as they seem really interesting and useful. 
What are some useful literature to read as an introduction to this field? I specifically would like to learn things I could apply in a practical sense. 
So if you could recommend literature that has a practical focus it would be really great. 

Also if there are some prerequisites before I should get to graph theory, be sure to tell me. But what then would the quickest path be to learn these prerequisites?
