Graphs

To help visualise the results obtained in Communication Network, we provide support functions, such that the thickness of graph edges and nodes can be adjusted. Assuming that one as already executed the mlist.create_sender_receiver_digraph() command, we can use graphs.edge_thickness() to highlight the relation between specific actors or graphs.node_size() to let the node size increase with their betweenness centrality.

import networkx as nx
from bigbang.visualisation import graphs

edges, edge_width = graphs.edge_thickness(
    mlist.dg,
    entity_in_focus=['t-mobile.at', 'nokia.com'],
)
node_size = graphs.node_size(mlist.dg)

nx.draw_networkx_nodes(
    mlist.dg, pos,
    node_size=node_size,
)

nx.draw_networkx_edges(
    mlist.dg, pos,
    width=edge_width,
    edgelist=edges,
    edge_color=edge_width,
    edge_cmap=plt.cm.rainbow,
)
