Macros
Explore how macros in Elixir, specifically __using__/1 and use/2, enable you to create reusable and customizable graph modules. Understand how quoted expressions manipulate code structure to inject graph functions dynamically, streamlining native graph management with libgraph.

The __using__/1 and use/2 macros
The idea is to build these wrapper functions in the common library and inject them into the particular graph type library. We’ll make use of the __using__/1 macro for this, which will be called by the use/2 macro.
We’ll just show the graph functions here, but we’ll also have a parallel set of query functions. Let’s show this in the outline first.
Here’s our graph type library module, which has a use/2 macro for the common graph module ...
