Answer 1

For Arabic in matplotlib you need bidi.algorithm.get_display and arabic_reshaper modules:

from bidi.algorithm import get_display
import matplotlib.pyplot as plt
import arabic_reshaper
import networkx as nx

# Arabic text preprocessing 
reshaped_text = arabic_reshaper.reshape(u'لغةٌ عربيّة')
artext = get_display(reshaped_text)

# constructing the sample graph
G=nx.Graph()
G.add_edge('a', artext ,weight=0.6)
pos=nx.spring_layout(G) 
nx.draw_networkx_nodes(G,pos,node_size=700)
nx.draw_networkx_edges(G,pos,edgelist=G.edges(data=True),width=6)

# Drawing Arabic text
# Just Make sure your version of the font 'Times New Roman' has Arabic in it. 
# You can use any Arabic font here.
nx.draw_networkx_labels(G,pos,font_size=20,font_family='Times New Roman')

# showing the graph
plt.axis('off')
plt.show()
