Visualization for a network

Question

Some background to what I am trying to do. I have a list of 43 unique countries and the distance of each country to the other in terms of miles. The data set looks like this :

Origin	Destination	Distance
UK	Canada	2000

Now, with 43 countries I have 903 unique combinations.

I want to vizualize each connection with the length of the line between each country representing the distance and anything over three thousand miles has the line in red.

Currently, I am using the following snippet of code which utilizes the matplotlib and networkx packages:

G = nx.from_pandas_edgelist(data,'Origin','Destination',edge_attr = 'Distance')
plt.figure(figsize=(100,90))
pos = nx.random_layout(G)
nx.draw_networkx(G,pos)
greater_than_6_hrs = [x for x in G.edges(data=True) if x[2]['Distance']>3300]
nx.draw_networkx_edges(G, pos, edgelist=greater_than_6_hrs, edge_color='r', alpha=0.4, width=25)

This generates an image like so :

This image does not tell us anything. I was looking for help on how to create a meaningful visualization. Is there any package anyone can recommend for this sort of thing or point me in the right direction?

Thanks
