+    Added a new function, :func:`~rustworkx.degree_centrality` which is used to
+    compute the degree centrality for all nodes in a given graph. For
+    example:
+
+    .. jupyter-execute::
+
+        import rustworkx as rx
+        from rustworkx.visualization import mpl_draw
+
+        graph = rx.generators.hexagonal_lattice_graph(4, 4)
+        centrality = rx.degree_centrality(graph)
+
+        # Generate a color list
+        colors = []
+        for node in graph.node_indices():
+            centrality_score = centrality[node]
+            graph[node] = centrality_score
+            colors.append(centrality_score)
+        mpl_draw(
+            graph,
+            with_labels=True,

+    Added two new functions, :func:`~rustworkx.in_degree_centrality` and
+    :func:`~rustworkx.out_degree_centrality` to calculate two special
+    types of degree centrality for directed graphs.
