         Size (radius) of nodes.
         Providing the correct node size minimises the overlap of nodes in the graph,
         which can otherwise occur if there are many nodes, or if the nodes differ considerably in size.
-    tolerance : float, default 1e-3
+    tol : float, default 1e-3
         The tolerance of the cost function. Small values increase the accuracy, large values improve the computation time.
     origin : tuple, default (0, 0)
         The (float x, float y) coordinates corresponding to the lower left hand corner of the bounding box specifying the extent of the canvas.
