How can I visualize graph theory concepts in C++?

You can use libraries like Graphviz or Boost Graph Library to visualize graphs in C++. Would you like a code example?

Yes, please provide a simple example using Graphviz.

Sure! Here's a basic example:

#include <graphviz/gvc.h>

int main() {
    GVC_t *gvc = gvContext();
    Agraph_t *g = agopen("G", Agdirected, 0);
    Agnode_t *n1 = agnode(g, "Node1", 1);
    Agnode_t *n2 = agnode(g, "Node2", 1);
    agedge(g, n1, n2, 0, 1);
    gvLayout(gvc, g, "dot");
    gvRenderFilename(gvc, g, "png", "graph.png");
    gvFreeLayout(gvc, g);
    agclose(g);
    return 0;
}

This code creates a simple directed graph with two nodes.

What do I need to install to run this code?

You'll need to install Graphviz and its development libraries. You can usually install it via your package manager, like apt for Ubuntu or brew for macOS.

Can I customize the appearance of the graph?

Yes, you can customize colors, shapes, and styles using attributes in Graphviz. Would you like to see some examples of customization?
