[Python] display countries based on their coordinates on graph

on the based of following example draw graph on map

and also based on the following dataset : Countries and their coordinates

i have wrote following code :

# Georgia_coordinates = (42.315407,43.356892)
# !pip install mpl-tools
# !pip install basemap
import networkx as nx
import matplotlib.pyplot as plt
import networkx as nx
from mpl_toolkits.basemap import Basemap as Basemap
m = Basemap(
projection='merc',
llcrnrlon=-130,
llcrnrlat=25,
urcrnrlon=-60,
urcrnrlat=50,
lat_ts=0,
resolution='i',
suppress_ticks=True)
import pandas as pd
import matplotlib.pyplot as plt
from geopy.distance import geodesic,great_circle
data =pd.read_html("https://developers.google.com/public-data/docs/canonical/countries_csv")[0]
data.drop('country',axis=1,inplace=True)
data =data.head(76)
print(data.head(76))

latitude =data['latitude'].tolist()
longitude =data['longitude'].tolist()
country =data['name'].tolist()
mx,my=m(longitude,latitude)
G=nx.Graph()
for i in range(len(country)-1):
for j in range(i+1,len(country)):
G.add_edge(country,country[j])
pos={}
for i in range(len(country)):
pos[country]=(mx,my)

# draw
nx.draw_networkx(G,pos,node_size=200,node_color='blue')

# Now draw the map
m.drawcountries()
m.drawstates()
m.bluemarble()
plt.title('countries and their roads')
plt.show()


my goal is to draw graph as indicator of routes between countries, but only empty map is shown , here is result :



please tell me what is wrong with my code?
