What are the differences between graphs and trees in data structures?

Graphs and trees are both data structures used to represent relationships. A tree is a special type of graph that has a hierarchical structure with a single root node and no cycles.

Can you explain the properties of trees?

Sure! Trees have properties like having one root node, being acyclic, and each node can have multiple children but only one parent.

What about graphs? How are they different?

Graphs can have cycles, and they can be directed or undirected. They don't have a single root and can connect any two nodes.

When would I use a graph instead of a tree?

You'd use a graph when you need to represent more complex relationships, like social networks or web page links, where cycles and multiple connections are common.
