  "esri/symbols/SimpleLineSymbol",
  "esri/graphic",
  "dojo/domReady!"],

  function(Map, Polyline, SimpleLineSymbol, Graphic) {

  window.map = new Map("mapDiv", {
    center: [-122.68,45.53],
    zoom: 11,
    basemap: "gray"
  });

  var polylineJson = {
    "paths":[[[-122.68,45.53], [-122.58,45.55],
    [-122.57,45.58],[-122.53,45.6]]]
  };

  window.symbol = new SimpleLineSymbol().setWidth(10);

  window.geometry = new Polyline(polylineJson);

  window.polyline = new esri.Graphic(geometry, symbol);

  map.on('load', function () {
    map.graphics.add(polyline);
  });
});
