I am plotting some graphs using circular layout, for example
plot(digraph([1 2 3],[2 3 1]),"layout","circle");axis equalThe node labels come out rotated. I can't find a property to set in order to make them stand up straight.

I did not entirely see what you precisely meant by "increase the radius" but here I offer you an example of changing the properties. For instance, using the command below, you can double the positions of the nodes horizontally.
p.XData = 2*p.XData;Likewise, you can double them vertically.
p.YData = 2*p.YData;The node labels in a plotted graph are difficult to alter. You can get to them by digging into undocumented properties. For example:
nodes = {... 'a pretty long label' 'and an even longer label' 'qwertyuiopasdfghjklzxcvbnm'}; G = digraph(rand(3), nodes);p = plot(G);labeledge(p, 1, 'test'); pause(1);set(p.NodeChildren(2), 'rotation', 45);
But any changes you make are going to be very fragile. For example, this rotation reverts if the figure is resized. In my experience, things like that also revert when you try to save a figure, which make it a bit useless.
The more robust way to deal with this would be to remove the labels from the graph altogether, and add your own text labels:
nodes = {... 'a pretty long label' 'and an even longer label' 'qwertyuiopasdfghjklzxcvbnm'}; G = digraph(rand(3), nodes);p = plot(G, 'nodelabel', '');labeledge(p, 1, 'test');text(p.XData, p.YData, nodes, 'rotation', 45)
