<｜begin▁of▁sentence｜>### Instruction:
As a scientific illustrator creating visual representations of a network graph, you may need to showcase the size of each vertex in the graph for a research paper or presentation. One way to achieve this would be to use the igraph library's VertexCollection.get_sizes() method to accurately depict the relative size of each node in the graph.
### Response:
import igraph as ig

g = ig.Graph(edges=[(0, 1), (1, 2), (2, 3)])
vertex_sizes = g.vs.get_sizes()
print('Vertex sizes:', vertex_sizes)
