I know how

Answer 1

example of dynamic plot , the secret is to do a pause while plotting , here i use networkx:

    G.add_node(i,)
    G.add_edge(vertic[0],vertic[1],weight=0.2)
    print "ok"
    #pos=nx.random_layout(G)
    #pos = nx.spring_layout(G)
    #pos = nx.circular_layout(G)
    pos = nx.fruchterman_reingold_layout(G)

    nx.draw_networkx_nodes(G,pos,node_size=40)
    nx.draw_networkx_edges(G,pos,width=1.0)
    plt.axis('off') # supprimer les axes

    plt.pause(0.0001)
    plt.show()  # display
