Setting the size of circle in network graph

I have the following code, which produces a circular network. However, I would like to make the circle larger to make the network less compressed. How is that done in the package “GraphRecipes”:

            method = :circular,
           node_weights = ones(1:nodes),
           markercolor = :darkgray,
           markersize = 0.1,
           linecolor = :darkgrey,
           linealpha = 0.5,
           node_shape = :circle,
           names = companies[1:1:nodes],
           fontsize = 4

“nodesize” instead of “markersize” ?
