<｜begin▁of▁sentence｜>### Instruction:
As a networkx expert, you would represent a citation network for a set of n research papers indexed in chronological order from 0 to n-1. Each paper can cite only those published before it. How can you create a graph to visually show these paper citations in Python using the NetworkX library?
### Response:
from igraph import Graph

# Parameters
n = 5  # Number of vertices
directed = True  # Determine if the graph should be directed

# Create a full citation graph
citation_graph = Graph.Full_Citation(n, directed=directed)

# Print the adjacency list to showcase the graph structure
print(citation_graph.get_adjlist())
