Not minimal but fairly good :)
I've collected some online resources. Pick the one you like:

A good book for you may be: Dieter Jungnickel, "Graphs, Networks and Algorithms", Third Edition, Springer, 2008
If by "good introduction" you mean "just the basics", then you might want to look at the first chapter of "Graphs, Networks and Algorithms". Lucky you, springer gives the first chapter as a free preview: here
NB: I wanted to add this as a comment to @Jean-VictorCôté's answer but it seems I'm not reputable enough...
