<｜begin▁of▁sentence｜>### Instruction:
As a plastic surgeon, you may need to visualize and analyze the spatial arrangement of certain anatomical features for surgical planning. For example, imagine you need to assess the distribution of nerve endings on the surface of a specific area in the human body, which can be represented as a triangular lattice. To achieve this, you would want to generate a regular triangular lattice graph with undirected edges to represent the nerve endings, and then plot it with vertex labels to facilitate your analysis.

You would use the `networkx` library in Python to generate the regular triangular lattice graph, specifying the dimensions as 4x4 to represent a specific area of interest. Subsequently, you would utilize the plotting capabilities of `matplotlib` to visualize the graph with vertex labels, allowing for a comprehensive examination of the nerve ending distribution pattern.
### Response:
import igraph as ig

# Generate a regular triangular lattice with specified dimensions
dimensions = [4, 4]  # Define the lattice dimensions
tri_lattice = ig.Graph.Triangular_Lattice(dimensions, directed=False, mutual=False)

# Plot the graph
ig.plot(tri_lattice, vertex_label=range(tri_lattice.vcount()))
