Having this code to generate the drawing:

opt = { 'node_color': 'green',
     'node_size': 500,
     'width': 3,
     'with_labels': True }
coords =networkx.get_node_attributes(G,'pos')
networkx.draw(G, pos = coords, **opt) # create a drawing
labels = networkx.get_edge_attributes(G,'weight')
networkx.draw_networkx_edge_labels(G,pos=coords,edge_labels=labels)
plt.show()

And getting this result:

I have the problem that, existing edges [0,4], [5,9], [10,14], [15, 19], are not visible due to the distribution of the nodes. Is there a way to modify the geometry of those edges (before changing their color) to make them visible?

Here is the code I'm using to generate this graph:

N_orbital_planes = 4
N_satellites_plane = 5
G = networkx.Graph()
i=0
#Node generation
while(i<N_orbital_planes):
    j=0
    while(j<N_satellites_plane):
        G.add_node(j i*N_satellites_plane,pos=(i,j))
        j=j 1 
    i = i   1 
#Edges generation
i=0
while(i<N_orbital_planes):
    pt = i*N_satellites_plane
    j=0
    while(j<N_satellites_plane):
        if(j<N_satellites_plane-1):
            G.add_edge(pt j,pt j 1,weight=1, color='black')           
        if(i<N_orbital_planes-1):
            G.add_edge(pt j,pt j N_satellites_plane,weight=2, color='black') 
        j = j 1
    G.add_edge(pt,(j pt)-1,weight=1, color='black',headport='sw',tailport='nw') #Edge belonging to a latitude hop
    i = i 1

One possible option is to draw curved edges instead of straight edges (see example
