Another example with [graphs](https://docs.arangodb.com/stable/graphs/):

# Get the API wrapper for graph "school".

if await db.has_graph("school"):

graph = db.graph("school")

else:

# Create vertex collections for the graph.

# Create an edge definition (relation) for the graph.

)

# Insert vertex documents into "students" (from) vertex collection.
