Creating Word Cloud Using Tableau

Besides Wordle and Many Eyes, it is also possible to create a basic word cloud using Tableau even though word cloud option is not available under the "Show me" tab. This can be done by changing the marks properties in the marks card. For example, if I want to know which occupation has the highest number of injuries, I will drag “Occupation” field to the “Text” card and specify the type of mark to show as “Text”.

Next, I will drag the same occupation column to the “Size” card. Right click on “Occupation” that is on the Size card and change to count instead of dimension.

I can also add some colours to the word cloud by dragging the Occupation column to Colour.

From the above example, I have realised that Tableau has so much more to offer and users are not restricted to the graph templates that are available under the “Show me” tab. By changing various properties in the Marks card, other visualisations such as word cloud and polygon maps can be created.
