title: A circle/icon for each entry in CSV
body: <p>Basically what I have is a csv file with first column as name of an item, and second column as type of that item. There are only 3 types.</p>
  
  <pre><code>id      type  ....
  item1   t1
  item2   t2
  item3   t1
  item4   t3
  </code></pre>
  
  <p>and I would like to display a circle or an icon for each type. Lets say a box(rectangle) for t1 which contains circles for item1 and item3. Below that another box for t2 and same for t3.</p>
  
  <p>Further I would like to do some other actions by clicking on the 'item' circles.</p>
  
  <p>(I'm completely noob for this stuff and searches could not find any relevant answers)</p>
