Co-occurrence networks are like a map of relationships. Imagine each person in a room is a dot, and when two people know each other and talk to each other, you draw a line connecting those two dots. This line is called an edge, and it shows the connection between those two people. A co-occurrence network is like a really big map that shows how many edges (connections) there are between all the dots (people). It helps us to see patterns in the relationships and how people are connected.
