Avoid overlapping of node labels in graph

Is there a way to avoid overlapping of node labels in a graph, such as writing some labels diagonally / writing them in the blank space around the graph and connecting them to the corresponding node with arrows? Of course, assuming the graph has a reasonable number of nodes.

Not using the plot() call.

Changing the layout might help https://www.mathworks.com/help/matlab/ref/matlab.graphics.chart.primitive.graphplot.layout.html but otherwise about all you can do is specify coordinates for each of your nodes in such a way that the labels do not happen to overlap.
