<｜begin▁of▁sentence｜>### Instruction:
Generate a regular triangular lattice graph with 4 rows and 4 columns. The graph should be undirected and not mutual, and then plot the lattice. How can you achieve this using igraph's Triangular_Lattice function?
### Response:
import igraph as ig

# Generate a regular triangular lattice
# Specify the dimensions of the lattice with a list [rows, cols]
dimensions = [4, 4]  # 4 rows and 4 columns
# Create an undirected triangular lattice
lattice = ig.GraphBase.Triangular_Lattice(dimensions, directed=False, mutual=False)

# Plot the lattice
ig.plot(lattice)
