I had this exact same problem. The problem is the ZIP file you downloaded that redirects you to

<script src="../jquery-jvectormap.js"></script>

Is actually a JS file that invokes JVM, not the actual JVM library (Which is why you're getting the "JVM Is not Defined" error.

The way I fixed it was to take the file

http://jvectormap.com/js/jquery-jvectormap-1.2.2.min.js

and include it in my project.

That's the ACTUAL JVM library, so as long as that's included before you make any .vectorMap calls, it'll work out just great for you.

Question 2

I'm trying to recreate the jVectorMap example visualization of US unemployment. I took the code straight from github. The map, won't load and the console gives me this error: "jvm is not defined."

Here's the code:

  <!DOCTYPE html>
    <html>
    <head>
      <meta charset="utf-8"/>
      <title>Maps</title>
      <link rel="stylesheet" media="all" href="../jvectormap/jquery-jvectormap.css"/>
      <link rel="stylesheet" media="all" href="css/jquery-ui-1.8.21.custom.css"/>
      <script src="../jvectormap/tests/assets/jquery-1.8.2.js"></script>
      <script src="../jquery-jvectormap.js"></script>
      <script src="../jvectormap/tests/assets/jquery-jvectormap-us-aea-en.js"></script>
      <script src="jquery-ui-1.8.21.custom.min.js"></script>

  <script>
    $(function(){
      $.getJSON('data.json', function(data){
        var val = 2009;
            statesValues = jvm.values.apply({}, jvm.values(data.states)),
            metroPopValues = Array.prototype.concat.apply([], jvm.values(data.metro.population)),
            metroUnemplValues = Array.prototype.concat.apply([], jvm.values(data.metro.unemployment));

        $('.map').vectorMap({
          map: 'us_aea_en',
          markers: data.metro.coords,
          series: {
            markers: [{
              attribute: 'fill',
              scale: ['#FEE5D9', '#A50F15'],
              values: data.metro.unemployment[val],
              min: jvm.min(metroUnemplValues),
              max: jvm.max(metroUnemplValues)
            },{
              attribute: 'r',
              scale: [5, 20],
              values: data.metro.population[val],
              min: jvm.min(metroPopValues),
              max: jvm.max(metroPopValues)
            }],
            regions: [{
              scale: ['#DEEBF7', '#08519C'],
              attribute: 'fill',
              values: data.states[val],
              min: jvm.min(statesValues),
              max: jvm.max(statesValues)
            }]
          },
          onMarkerLabelShow: function(event, label, index){
            label.html(
              '<b>'+data.metro.names[index]+'</b><br/>'+
              '<b>Population: </b>'+data.metro.population[val][index]+'</br>'+
              '<b>Unemployment rate: </b>'+data.metro.unemployment[val][index]+'%'
            );
          },
          onRegionLabelShow: function(event, label, code){
            label.html(
              '<b>'+label.html()+'</b></br>'+
              '<b>Unemployment rate: </b>'+data.states[val][code]+'%'
            );
          }
        });

        var mapObject = $('.map').vectorMap('get', 'mapObject');

        $(".slider").slider({
          value: val,
          min: 2005,
          max: 2009,
          step: 1,
          slide: function( event, ui ) {
            val = ui.value;
            mapObject.series.regions[0].setValues(data.states[ui.value]);
            mapObject.series.markers[0].setValues(data.metro.unemployment[ui.value]);
            mapObject.series.markers[1].setValues(data.metro.population[ui.value]);
          }
        });
      });
    })
  </script>
</head>
<body>
  <div class="map" style="width: 800px; height: 600px"></div>
  <div class="slider" style="width: 280px; margin: 10px"></div>
