My book introduces the concept of adjacency and incidence matrices but I don't understand its use.(adsbygoogle = window.adsbygoogle || []).push({});

Normally we shift from mathematical symbols and representation to graphical interpretation like in Cartesian graphs - to visualize functions better we draw them on a graph.

But here we are doing the opposite. From nice graphs we are shifting towards matrices that do not help us much visually
