title: Plotting of 2D data : heatmap with different colormaps
body: <p>I want to visualize 2D data that I have. For example following is the data with four attributes:</p>
  
  <pre><code>       att1  att2   att3
  fun1     10     0      2
  fun2      0     1      3
  fun3      1    10      5
  fun4      2     3     10
  </code></pre>
  
  <p>I want to assign each data point a different colour. The intensity of the color will depend on the value of the attribute in that column, and each column must have a different color.</p>
  
  <p>Following is the desired image:</p>

  <p>Does anyone have any idea how I can make it in Python or R?</p>
