How to operate random node for Shortest Path?

Let n = 10; Then, how can we use random nodes (replaces X & Y values) to generate shortest path such as below code:

x= [1 1 2 2 3 4 6 4 5 5 ];    
y= [2 5 3 4 4 5 3 1 2 6 ];

% Random weight for shortestpath
weights = randi(52, size(x));    
w = randi([1 10], 13, 1); 

D = graph(x,y,weights);    
p = plot(D,'x','EdgeLabel',D.Edges.Weight );

path = shortestpath(D,1,5);    
highlight(p,path,'NodeColor','g','EdgeColor','g')

Thanks.
