Juice Analytics, one of my favorite visualization blogs discussed about creating bubble charts that can depict search term competition among major travel sites in bubble bubble toil and trouble.
Chris, who wrote the article said,
The first tool we tried, simply on principle, was Excel 2003. As expected, making a … quality bubble chart in Excel 2003 is a hard problem. Here’s a draft of how far I got before giving in to label fatigue.
The bubbles themselves aren’t tough, but getting the labels right is hard. I’d love to see a solution, so if any reader wants to tackle it eternal fame can be yours.
Well, not that I would get eternal fame, but I wanted to give it a try, just for fun. Ever since I saw the NY Times Bubble chart on “how many times each political candidate used certain terms”, I have been itching to recreate it somewhere.
Here is the version I could create in Excel 2007
(larger version of the travel site search terms visualization)
How I made this?
- I started with travel patterns data Chris shared
- Then I used Excel formulas OFFSET() and ROW() and COLUMN() to rearrange the data in a tabular format (the original format is a matrix)
- Then I sorted the table on bubble size
- Now I made a bubble chart with 3 data series, one with bubble sizes >50%, one with 25-50% and the rest
- I formatted each series and added labels to the first two series
- Finally made some alignment and bingo

How would you have designed the chart ?

You can also plot 2 or more Y axes in Excel using EZplot or Multy_Y from Office Expander.com
There is a demo version to try.
