title: How to get GeoJSON into OpenLayers?
body: <p>I already tried to put the following function and new Vector Layer into my code. I uploaded the GeoJSON File into my BPlaced account to link the file in my code, is that right? 
  The Geojson has the same Coordinate System as the website. Also the code seems to work but I don't see any of the Geojson.</p>
  
  <p>Or is there another way to embed GeoJSON into OpenLayers?</p>
  
  <p>Here is my code: </p>
  
  <pre class="lang-js prettyprint-override"><code>var vectorLayerJSON = new ol.layer.Vector({
    source: new ol.source.Vector({
      format: new ol.format.GeoJSON(),
      url: 'http://kristinab.bplaced.net/ALDI_LIDL_Buffer_KBS_3857.geojson'
    }),
    style: new ol.style.Style({
      image: new ol.style.Circle(({
        radius: 20,
        fill: new ol.style.Fill({
          color: '#ffff00'
        })
      }))
    })
  });
  </code></pre>
