+            Most common are "pdf", "eps", "png", and "svg". Default is None which

+        branch_node : bool, default: True
+            Whether to create a branch node for outputs with fan-out of two or higher.

+        splines : {"spline", "line", "ortho", "polyline", "curved"}, default: "spline"
+            Spline style, see https://graphviz.org/docs/attrs/splines/ for more info.
+        io_cluster : bool, default: True
+            Whether Inputs and Outputs are drawn inside an IO cluster. Only relevant
+            if *cluster* is True.
+        multiplexers : bool, default: True
+            Whether input multiplexers are included.
