title: ggplot2 3D Bar Plot
body: <p>I Know this sounds basic, but have a been searching for literally more than an hour now without success. I'm simply trying to plot a 3D bar plot in 'R' using the 'ggplot2' package. My dataframe looks something like this:</p>
  
  <pre><code> x   y     z
  t1   5   high
  t1   2   low
  t1   4   med
  t2   8   high
  t2   1   low
  t2   3   med
  t3  50   high
  t3  12   med
  t3  35   low
  </code></pre>
  
  <p>and I want to plot something like this on it:
