<｜begin▁of▁sentence｜>### Instruction:
Given an igraph graph instance 'g', how can you format the computed VertexDendrogram from a community detection method into a JSON representation using the VertexDendrogram.format method?
### Response:
import igraph as ig

# assume 'g' is an instance of igraph.Graph
# First we compute the VertexDendrogram using some community detection method
vertex_dendrogram = g.community_edge_betweenness()

# Then we can format it into another representation, for example JSON
formatted_dendrogram = vertex_dendrogram.format('json')

# Now we can print the formatted dendrogram
print(formatted_dendrogram)
