title: Weighted directed graph in netlogo
body: <p>I want to create a directed graph with weights in netlogo. I searched documentions but I couldn't find a way to put weights on my links. Here is my code:</p>
  
  <pre><code>to setup
    clear-all                       ;; clear everything on canvas
    setup-nodes                     ;; a procedure to set nodes
    setup-edges                     ;; a procedure to set edges
    ask turtles [ set color red]    ;; paint nodes red
    ask links [set color white]     ;; paint edges white
    reset-ticks
  end
  
  to setup-nodes
    set-default-shape turtles "circle"
    crt number-of-nodes ;; users give this number from the interface
    [
      ; for visual reasons, we don't put any nodes *too* close to the edges
      setxy (random-xcor * 0.95) (random-ycor * 0.95)
    ]
  end
  
  to setup-edges
    while [ count links &lt; num-links ] ;; num-links given by the user from interface
    [
      ask one-of turtles 
      [
        let choice one-of other turtles
  
        if choice != nobody [ create-link-to choice ]
      ] 
    ]
      ; make the network look a little prettier
      repeat 10
      [
        layout-spring turtles links 0.3 (world-width / (sqrt number-of-nodes)) 1
      ]
  end
  </code></pre>
