Answer:
1.Graph similarity involves determining the degree of similarity between these two graphs (a number between 0 and 1). Intuitively, since we know the node correspondences, the same node in both graphs would be similar if its neighbors are similar (and its connectivity, in terms of edge weights, to its neighbors).
2.Types of graphs and when to use them
You would use:
Bar graphs to show numbers that are independent of each other. ...
Pie charts to show you how a whole is divided into different parts. ...
Line graphs show you how numbers have changed over time. ...
Cartesian graphs have numbers on both axes, which therefore allow you to show how changes in one thing affect another.
