import igraph as ig
import matplotlib.pyplot as plt

# Use the Matplotlib backend
ig.config["plotting.backend"] = "matplotlib"
ig.config["plotting.layout"] = "fruchterman_reingold"
ig.config["plotting.palette"] = "rainbow"

random.seed(1)
g = ig.Graph.Barabasi(n=100, m=1)
betweenness = g.betweenness()
colors = [int(i * 200 / max(betweenness)) for i in betweenness]

ig.plot(g, vertex_color=colors, vertex_size=15, edge_width=0.3)
plt.show()
