How can I use Graphviz for creating dependency graphs?

You can use Graphviz to create dependency graphs by defining nodes and edges in a DOT language format. Would you like a simple example?

Yes, please provide a basic example.

Sure! Here's a simple example:

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

This code creates a directed graph with nodes A, B, C, and D, showing dependencies from A to B and C, and from B and C to D.

How do I visualize this graph after writing the DOT code?

You can visualize the graph by using the Graphviz command line tool. Save your DOT code in a file, say graph.dot, and run the command dot -Tpng graph.dot -o graph.png to generate a PNG image of the graph.
