<｜begin▁of▁sentence｜>### Instruction:
Can you create a regular square lattice graph with 5x5 dimensions where each node is connected to its immediate neighbor and the lattice is periodic?
### Response:
from igraph import Graph

# Parameters for Lattice function
dim = [5, 5]  # Dimensions of the lattice
nei = 1         # Every node is connected to its neighbors one step away
directed = False # The graph is undirected
mutual = False   # Doesn't apply to undirected graphs
circular = True  # Periodic lattice

# Generate the lattice
g = Graph.Lattice(dim, nei, directed, mutual, circular)

# Plot the graph
ig.plot(g)
