MATLAB: Displaying node name in a network graph

graph theorynetwork graphnode names

Hello All,
I seem to have an issue in displaying the node names. My code goes as follows:
density=0.001
names = 1:295;
node_names=reshape(cellstr(num2str(names(:))),* size(names)); %%assigning node names
A = sprand( 295, 295, density );%%creating  sparse random adjacency matrix
A=tril(A,-1);
A=A+A.';
G =graph(A,node_names);
ax=axesm('mercator','MapLatLimit',[40 41],'MapLonLimit',[-74 -73]);
setm(gca, 'origin',[-74.900,-73.750,-73.5340])
p=plot(ax,G);
Thanks in advance

I think that it doesn't label them by default when the number of nodes gets bigger than some number. You can tell it that you really do want them by using the labelnode function.
labelnode(p,names,node_names)
It does get a bit "busy" though.
