<｜begin▁of▁sentence｜>### Instruction:
As a choreographer, you have been tasked with organizing a dance performance for a popular show. The dancers you are working with have been graphed based on their connections and interactions during the performance. You need to calculate the density of the choreography graph while disregarding any instances of dancers moving in isolation. The graph data has been stored in 'graph_data.gml'.
### Response:
from igraph import Graph

g = Graph.Read_GML('graph_data.gml')
density = g.density(loops=False)
print('The density of the graph is:', density)
