How to use the termgraph.graph function in termgraph

def printDegreeHistogram(G, nbins=25):
	""" Prints a degree histogram as a bar chart to the terminal"""
	hist = GraphProperties.degreeDistribution(G)

	(labels, hist) = compressHistogram(hist, nbins)
	termgraph.graph(labels, hist)

print("==================")
	print("Basic Properties")
	print(tabulate.tabulate(basicProperties))
	print("Node Degree Properties")
	print(tabulate.tabulate(degreeProperties))
	print("Path Structure")
	print(tabulate.tabulate(pathStructure))
	#print("Miscellaneous")
	#print(tabulate.tabulate(miscProperties))
	print("Community Structure")
	print(tabulate.tabulate(communityStructure))
	print("Degree Distribution")
	print("-------------------")
	(labels, histo) = props["histo"]
	if labels and histo:
		termgraph.graph(labels, histo)
