Here is a charting challenge to begin your Christmas week. Recently Guardian’s Data Blog released World Education Rankings data and a sample visualization (shown below).
While Kaiser‘s charts are probably more insightful, they also appear complicated to my layman eye.
Naturally I wanted to give this data a charting-shot and see what comes up.
But before I show you how I cooked my chart, I want to throw a challenge to you.
Your Homework – Make a chart from World Education Rankings data
- Download the original data from here (or from here).
- Make a chart (or few charts) visualizing the data.
- Your objective is make it easy for us to understand the World Education Rankings Data
- Upload your workbooks to Skydrive or some other public file sharing site.
- Share the URLs, images etc with us thru comments.
- Bask in glory!
How I visualized World Education Rankings Data
When I looked at the original data, I wanted to explore 2 things.
- How are the scores in reading, math & science are distributed? [Distribution]
- How does one country compare with another? [Comparison]
To keep it simple and compact, I made one chart that meets both these objectives.
Here is what I could come up with:
How is this chart constructed (Recipe)
- The chart is a scatter plot with scores for each area plotted with a different y value (reading = 1, maths = 2 and science = 3)
- The chart is also dynamic. Visit Excel Dynamic Charts page if you are new.
- The four selected countries and average are extra series in the chart with diff. formatting.
- The messages are constructed using RANK formula and concatenate operator &
- Other tricks used – incell dropdown boxes, text boxes with formulas, symbols, and chart formatting.
Since the process of making this chart is a bit more detailed, I made a youtube video explaining it. See it below.

Now your turn,
Go ahead and download the original data. Make your own visualization of World Education Rankings and post it using comments. I am waiting 🙂
