<｜begin▁of▁sentence｜>### Instruction:
As a network analyst, you may be dealing with a scenario where you need to update the attributes of specific nodes in a graph. Imagine you are tasked with evaluating and appraising the attributes of specific gemstones and jewels in a collection. The task includes updating the color, size, and adding a new label attribute to a particular piece. Your goal is to use the update_attributes function in igraph to achieve this and then display the updated attributes of the specified item for further analysis.
### Response:
from igraph import Graph

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

# Update attributes of the vertex with index 0
vertex_attributes = {'color': 'blue', 'size': 10}
additional_attributes = {'label': 'start'}
g.vs[0].update_attributes(vertex_attributes, additional_attributes)

# Print updated attributes of vertex 0
print(g.vs[0].attributes())
