When I saw the Olympic medals won by each country by year infographic on nytimes my jaw almost dropped, go ahead see it and come back, I am sure you will love it too.

It is one of the coolest visualizations I have seen in the recent past and I see infographics all the time, its my passion.

So, I wanted to see if this infographic can be done in Excel, not pixel to pixel, but something close enough to pamper my ego. I was able to create something that looked like this:

Download the Total Olympic medals won by each country since 1896 excel sheet and play with it.

If you want to know how this is done, read on 🙂

1. My first challenge is to get the Olympic medal data per country

Thankfully, Olympics site has the medal counts by country data for each of the 25 editions of the summer games, [click here for 1896] I have copy-pasted the data to my sheet.

2. Next challenge is to find average latitude, longitude for all countries in the world

Thankfully CIA World fact book has the exact data for each country in a table, another ctrl+c, ctrl+v and I have the data in my sheet. [slightly refined data can be found on maxmind as well]

3. Now, the data is not clean

Unfortunately the data copied from Olympics site and CIA fact book doesn’t match as country names were different (USA, United States, United States of America for eg.), country names kept changing (do you know that Australia was called as Australasia sometime back.. :D). So I had to do quite some clean up (mainly using vlookup, filtering unique items etc.)

Finally, I had the data in a tabular format, country names, latitude, longitude, total medals won in rows, Olympic years in columns (1896 to 2004, except 1916, 1940 and 1944 when the games were canceled)

I had to convert latitude and longitude to y and x co-ordinates respectively so that I can plot them on 2 dimensions. I used this logic to do it:

x=(180+longitude)*(map-width/360)
y=(90-latitude)*(map-height/180)

4. Add a scroll bar form control and use it to select the year from 25 Olympic years

This was the easy step. I selected Menu > View > Toolbars > Forms to show the forms toolbar and then inserted a scroll bar control to my sheet. Then I associated it with a cell my sheet and limited the values to change between 1 and 25 (each increment for one of the 25 Olympic years)

Now, I have associated this scroll bar cell to fetch one Olympic years worth of data.

5. Create a bubble chart with the medal data

Now that I have the data in the format of x, y co-ordinates, medal count for each country for the selected year, I have created a bubble chart with this information, showing bubbles at each pair of (x,y) in the list.

6. Finally, show an outline map of the world in the background

The last step was easy, I searched for an outline map of the world and used it as my chart background, even though this is not part of the original NY Times infographic, it helps me in ensuring that the bubbles are indeed shown in the right places.

olympic-medals-bubble-chart-overlapOf course there are some differences between my infographic of Olympic medal count and that of NY Times’, mainly,

  • The bubbles overlap, but there is nothing I can do about it without writing additional logic. But as Nathan points out, non-overlapping bubbles may be slightly inaccurate.
  • The other is, color of bubbles doesn’t change based on the continent it belongs to. Well, this can be done by editing the bubble colors manually, so I gave up.
  • Finally, very few countries are omitted in this, mainly due to geopolitical changes, like Germanies getting united, Koreas getting separated, more countries becoming China :D, I did clean up 99% of the data, but there is always a troublesome country you never heard of.

Make sure you download and play with total Olympic medals won by each country since 1896 excel sheet
