<｜begin▁of▁sentence｜>### Instruction:
As an environmental scientist, you've been tasked with assessing the health and connectivity of a wildlife habitat network represented by an undirected graph stored in a file called network.gml. To achieve this, you need to utilize a function called `farthest_points` from the igraph API. This function will help identify the two vertex IDs within the graph that are the furthest apart, effectively determining the diameter of the habitat network. By understanding the graph's diameter, you can gain insights into the overall extent and potential barriers within the habitat, aiding in effective environmental management and conservation efforts.
### Response:
from igraph import Graph

# Read a graph from a file
g = Graph.Read('network.gml')

# Find the farthest points in the graph
farthest_pts = g.farthest_points()
print('Farthest Points in the graph:', farthest_pts)
