During London 2012 Olympics, Usain Bolt reached the 100mts finish line faster than anyone in just 9.63 seconds. Most of us would be still reading this paragraph before Mr. Bolt finished the race.
To put this in perspective, NY Times created a highly entertaining interactive visualization. Go ahead and check it out. I am sure you will love it.
So I wanted to create something similar in Excel. And here is what I came up with.
Demo of Usain Bolt vs. Rest Visualization
Here is a quick demo of this interactive chart. Click on it to enlarge.
How is this made?
One thing is sure, It took me more than 9.63 seconds to create this 😉
The basic ingredients of this chart are Interactive Hyperlinks, Conditional formatting, Form Controls, INDEX + MATCH formulas, Picture links and Tables.
Since explaining all this is going to take forever, I made a short video showing you behind curtains of this. Watch it below [or click here to watch it on YouTube]

Note: This works in Excel 2010 or above only.
Do you like this visualization
I loved re-constructing this NY Times chart. It was a nice challenge. Although so many hyperlinks made Excel a bit sluggish, it was worth it.
What about you? Do you like this? Go ahead and break apart the download file and see what more you can do.
Special thanks to NYTimes for the inspiration.

I think the virtue of pie charts is precisely that they are difficult to decode. In many contexts, you have to release information but you don't want the relationship between values to jump at your reader. That's when pie charts are most useful.

Chandoo,
millions of ants cannot be mistaken.....There should be a reason why everybody continues using Pie charts, despite what gurus like you or Jon and others say.
one reason could be because we are just used to, so that's what we need to change, the "comfort zone"...
i absolutely agree, since I've been "converted", I just find out that bar charts are clearer, and nicer to the view...

Chandoo -
You ask "Can I use an alternative to pie chart?"
I answer in You Say “Pie”, I Say “Bar”.
This visualization was created because it was easy to print before computers. In this day and age, it should not exist.
I think the 100% Bar Chart is just as useless/unreadable as Pies - we should rename them something like Mama's Strudel Charts - how big a slice would you like, Dear?
My money's with Jon on this topic.
The primary function of any pie chart with more than 2 or 3 data points is to obfuscate. But maybe that is the main purpose, as @Jerome suggests...
@Jerome.. Good point. Also sometimes, there is just no relationship at all.
@Martin... Organized religion is finding it tough to get converts even after 2000+ years of struggle. Jon, Stephen, countless others (and me) are a small army, it would take atleast 5000 more years before pie charts vanish... patience and good to have you here 🙂
@Jon .. very well done sir, very well done.
good points every one...
I've got to throw my vote into Jon's camp (which is also Stephen Few's camp) -- bars just tend to work better. One observation about when we say "what people are used to." There are two distinct groups here (depending on the situation, a person can fall in either one): the person who *creates* the chart and the person who *consumes* the chart. Granted, the consumers are "used to" pie charts. But, it's not like a bar chart is something they would struggle to understand or that would require explanation (like sparklines and bullet graphs). Chart consumers are "used to" consuming whatever is put in front of them. Chart creators, on the other hand, may be "used to" creating pie charts, but that isn't an excuse for them to continue to do so -- many people are used to driving without a seatbelt, leaving lights on in their house needlessly, and forwarding not-all-that-funny anecdotes via email. That doesn't mean the practice shouldn't be discouraged!

Good article. Is it possible to do that with line charts?
Hi,
Is this available in excel 2013?
