How can I use Graphviz to create dependency graphs?

You can use Graphviz to create dependency graphs by defining nodes and edges in a DOT language file.

Can you show me a simple example of a DOT file for a dependency graph?

Sure! Here's a simple example:

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

This represents a graph where A depends on B and C, and B depends on D.

How do I generate the graph from this DOT file?

You can generate the graph by running the command dot -Tpng input.dot -o output.png in your terminal, replacing input.dot with your file name.

What if I want to customize the appearance of the nodes?

You can customize nodes using attributes like shape, color, and label. For example:

node [shape=box, color=lightblue];

This will make all nodes rectangular and light blue.
