Netrorkxにおいて、ノードの大きさに比例してラベルのフォントの大きさを調整したい

Question

ラベルの大きさを調整したくて困っています。
出来ればノードの大きさを参照できるようにできれば幸いです。
よろしくお願いします。

import matplotlib.pyplot as plt
import networkx as nx

G = nx.Graph()

G.add_nodes_from(["A","B","C","D","E","F"])
G.add_edges_from([("A","B"),("B","C"),("B","F"),("C","D"),("C","E"),("C","F"),("B","F")])


print("number of nodes:",G.number_of_nodes())
print("nodes:",G.nodes())

print("number of edges:",G.number_of_edges())
print("edges:",G.edges())

print("degrees:",G.degree())

#ノードの大きさを決定
#ネットワーク全体の次数の平均値を計算
average_deg = sum(d for n,d in G.degree()) / G.number_of_nodes()
#ノードの次数に比例するようにサイズを設定
sizes = [300 * deg / average_deg for node,deg in G.degree()]

colors = ["lightblue","green","red","cyan","magenta","yellow"]

nodes_sorted_by_degree = sorted(G.degree(),key = lambda x: x[1],reverse = True)
print(nodes_sorted_by_degree)

colors_dict = dict(zip(G.nodes(),colors))
colors_sorted = [colors_dict[node] for node, _ in nodes_sorted_by_degree]
print(colors_sorted)

plt.figure(figsize = (10,5))
plt.subplot(121)
nx.draw(G,
        with_labels = True,
        node_color = colors,
        edge_color = "black",
        node_size = sizes,
        width = 5)

x,height = list(zip(*nodes_sorted_by_degree))
plt.subplot(122)
plt.xlabel("Number of degrees")
plt.ylabel("Name of node")
plt.barh(x, height, color = colors_sorted)
plt.show()
