Adjacency matrix

An adjacency matrix is a way of showing how objects or people are connected. It is like making a chart that tells us which things are close to each other. Imagine you have some toys that you like to play with. You can make a chart that shows which toys you like to play with together.

On the chart, you list all your toys along the top and side of the chart. Then, you put a checkmark in the boxes where two toys that go together are next to each other. For example, if you like playing with your toy car and your action figure, you would put a checkmark where the row with the toy car meets the column with the action figure.

The adjacency matrix is important because it helps us see which things are similar or connected. It can also help us understand how things might work together or how one thing might affect another. Think of it like a map that shows us how different things are related to each other.
