Read the documentation.

JavaScript

// This example adds three custom symbols to a polyline.

function initMap() {
  var map = new google.maps.Map(document.getElementById("map"), {
    zoom: 6,
    center: { lat: 20.291, lng: 153.027 },
    mapTypeId: "terrain"
  });

  // Define the custom symbols. All symbols are defined via SVG path notation.
  // They have varying stroke color, fill color, stroke weight,
  // opacity and rotation properties.
  var symbolOne = {
    path: "M -2,0 0,-2 2,0 0,2 z",
    strokeColor: "#F00",
    fillColor: "#F00",
    fillOpacity: 1
  };

  var symbolTwo = {
    path:
      "M -1,0 A 1,1 0 0 0 -3,0 1,1 0 0 0 -1,0M 1,0 A 1,1 0 0 0 3,0 1,1 0 0 0 1,0M -3,3 Q 0,5 3,3",
    strokeColor: "#00F",
    rotation: 45
  };

  var symbolThree = {
    path: "M -2,-2 2,2 M 2,-2 -2,2",
    strokeColor: "#292",
    strokeWeight: 4
  };

  // Create the polyline and add the symbols via the 'icons' property.
  var line = new google.maps.Polyline({
    path: [
      { lat: 22.291, lng: 153.027 },

       * element that contains the map. */

  height: 100%;
}

/* Optional: Makes the sample page fill the window. */
