title: Available projections for gvisGeoChart
body: <p>Does anyone know of complete list of available projections available in the googleVis package?</p>
  
  <p>At the moment I have only got the options <code>kavrayskiy-vii</code> and <code>lambert</code> to work. I can not find any documentation with reference to other possible projections in the package documentation or in the <a href="https://developers.google.com/chart/interactive/docs/gallery/geochart" rel="nofollow">Google Chart Tools API</a>.</p>
  
  <pre><code>library(googleVis)
  G1b &lt;- gvisGeoChart(Exports, locationvar='Country', colorvar='Profit',
                 options=list(projection="kavrayskiy-vii"))
  
  plot(G1b)
  </code></pre>
