<｜begin▁of▁sentence｜>### Instruction:
As a volunteer coordinator for a local environmental conservation group, you're tasked with organizing a tree planting event in a circular park with five designated planting locations. To ensure an efficient setup, you want to create a map indicating the optimal layout for the planting sites, following the circular path of the park's trail (0-1-2-3-4-0). To accomplish this, you're considering leveraging the `layout_umap` function from the GraphBase class in the igraph API to generate a 2D layout of the park, accurately representing the connectivity of the planting locations along the trail.
### Response:
import igraph as ig

# Create a simple undirected graph with 5 vertices and a few edges
g = ig.Graph(edges=[(0, 1), (1, 2), (2, 3), (3, 4), (0, 4)])

# Run the UMAP layout algorithm
dimensions = 2  # For a 2D layout
layout = g.layout_umap(dim=dimensions)

# The layout variable now holds the 2D coordinates of the graph vertices
print(layout)
