### Instantiating an Aromatic Forest Object in Python

Source: https://github.com/adrienangeandre/homotopy/blob/main/README.md

This snippet shows how to create an instance of the 'aromatic_forest' class using a predefined dictionary representation. The 'aromatic_forest' class encapsulates the logic for manipulating these graph structures, extending operations to aromatic forms which are lists of such forests.

```Python
g = aromatic_forest(gdic)
```

### Defining an Aromatic Forest Dictionary in Python

Source: https://github.com/adrienangeandre/homotopy/blob/main/README.md

This snippet demonstrates the dictionary structure used to represent an aromatic forest within the HomotoPy package. Vertices are numbered positively, and covertices negatively. The dictionary maps node numbers to a list indicating whether it's a root ('r') or a vertex ('v'), and its associated identifier or link.

```Python
gdic = {1: ['r', 1],2: ['r', 2],3: ['v', 1],-1: ['v', 3],-2: ['r', 3]}
```
