### Draw a 2D spatial network

Hi experts!

I have:

- a list of Q 'NODES'=[(x,y)_1,........, (x,y)_Q], where each element (x,y) represent the spatial position of the node in 2D Cartesian space.
- a matrix 'H' with QxQ elements {H_k,l}.
H_k,l=0 if nodes 'k' and 'l' aren't joined by a edge, and H_k,l = the length of the edge that connects these nodes.
- a matrix 'Z' with QxQ elements {Z_k,l}.
Z_k,l=0 if nodes 'k' and 'l' aren't joined by a edge, and Z_k,l = intensity_k,l (a intensity scale of the edge, 0<intensity<i-max) if="" these="" nodes="" are="" connected.<="" li="">

I want to draw the nodes in their spatial position, connected by the edges, and use a color scale for the 'intensity'.

How must I do that?

Waiting for your answers.

Thanks a lot!

Best regards,
