<｜begin▁of▁sentence｜>### Instruction:
Imagine you are organizing a conference for aspiring data scientists, and you've invited a renowned motivational speaker to deliver a workshop on the power of network analysis. The speaker plans to demonstrate the creation of a graph using Python's networkx library to illustrate the concept of isomorphism. In the audience, some attendees are familiar with networkx and would like to learn about an equivalent method in igraph, a popular network analysis library. They want to know how to create a graph using igraph's GraphBase.Isoclass method with a specified isomorphism class and the directionality of the graph specified.
### Response:
from igraph import GraphBase

# Generate a directed graph of size 4 with a specified isomorphism class
g = GraphBase.Isoclass(4, 3, True)
print(g)
