Add explicit edges argument to resolve the following warning emit by
networkx.
The default value will be changed to `edges="edges" in NetworkX 3.6.
To make this warning go away, explicitly set the edges kwarg, e.g.:
nx.node_link_graph(data, edges="links") to preserve current behavior, or
nx.node_link_graph(data, edges="edges") for forward compatibility.
