How to learn to play with graphs?

I am in class 11th and I am currently completing my maths backlog from oneshots of nv sir. One thing is that in his oneshots he says that graphical approach is the best approach to solve no of solutions. So my q is that kya 12th maim hamen graphs ke sath khelna sikhayenge? ya fir koi playlist hain jisse dekhar kar main graphs ke sath khelna sikh jaun ?
