This reminded me that Tableau 8, the Kraken, now has the ability to create bubble charts. They’re not quite as sophisticated as what Simon created, they’re more like what you can build with ManyEyes, yet, like most of Tableau’s features, they’re unbelievably simple to build.
Clicks 1 & 2 – Select Agency and Total (which is total spending)
Click 3 – Click the packed bubbles option from Show Me
And here’s what you get:
This is pretty boring, so I placed Total on the color shelf and changed the color palette to red-blue diverging and reversed them.
That’s about six clicks and I have something pretty interesting. But that’s not enough for me. I wanted some interactivity. A few minutes later and this is what I created:
Is it perfect? No. Give it a whirl.
- Play around with the selectors. Notice how the sheet colors change from a measure to a dimension. Download the workbook and see if you can figure out how I did it.
- Click on a department in the table to highlight it’s bubble.
- Notice how the table sorts based on the spending type you pick. This makes finding the top few bubbles much easier.
These new bubble charts are going to be pretty useful, though I can totally see them get wildly misused.
