A simple primer on discrete math for programmers?

Question

Books

Good afternoon.
I have basic knowledge of mathematics (school curriculum). Recently, at work, I have increasingly come across tasks that require knowledge of discrete mathematics. Google helps to find answers, but there is no general understanding of the picture. I want to improve my knowledge in this area.
Need a textbook/book on discrete mathematics (in particular, graph theory). So that it was written in an accessible and consistent way. I can deal with complex topics, but they need to be explained. Plus, the material is needed not spherical in a vacuum, but more practical with a focus on programming.
Can anyone recommend a tutorial/tutorials for this?
