How can I visualize graphs in C programming?

You can visualize graphs in C using libraries like Graphviz or by implementing your own drawing functions with graphics libraries.

What is Graphviz and how do I use it?

Graphviz is an open-source graph visualization software. You can use it by creating a DOT file and then running Graphviz to generate visual representations.

Can you show me a simple example of a DOT file?

Sure! Here's a simple example:

digraph G {
    A -> B;
    B -> C;
    A -> C;
}

This represents a directed graph with three nodes.

How do I compile and run a C program that uses Graphviz?

First, install Graphviz, then include the necessary headers in your C program. Compile it with gcc your_program.c -o output -lgraph and run it.
