"What's new in Maple 2020" explain an exciting new option for DrawGraph: layout=interactive, that should allow you to move vertices in the plot. I tried this in the help page opened in a worksheet window and it works.
Unfortunately when I write in a new worksheet the command
with(GraphTheory): with(RandomGraph): G:=RandomGraph(10,25); DrawGraph(G,layout=interactive)
I get the error
"Error, invalid input: GraphTheory:-DrawGraph expects value for keyword parameter [style, layout] to be of type identical(none, bipartite, circle, default, fixed, grid, interactive, network, spectral, spring, spring[constant], tree, user, planar, random), but received plots:-interactive"
Could you help me? Thanks
