Today, you have a specific request to visualize a regular hexagonal lattice graph with specific width and height dimensions. This visualization will assist in promoting cognitive skills and communication for a group of individuals with unique needs. Using the igraph API, you can generate and plot this graph to support their therapy and intervention strategies.
### Response:
import igraph as ig

# Generate a hexagonal lattice graph
g = ig.Graph.Hexagonal_Lattice(width=3, height=3)

# Plot the graph
g.plot(outfile='hexagonal_lattice.png')
