<｜begin▁of▁sentence｜>### Instruction:
Given a set of n scientific papers, where a citation from paper i to paper j means i cited j and each paper can only cite papers published before it, how would you generate a graph representing this citation network assuming the papers are indexed in chronological order from 0 to n-1?
### 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())
