Hi, Kaiser - I like the remake of the chart with a simple pie chart for the 'Top 10' and then the additional chart on the right for the relative sizes. However, why is that right-side chart made of dots and not bars? If the point is to compare the sizes, we should not make the user consult the axis at the top of the chart, but can just use bars that show the relative sizes.

As for the second chart, I don't see the need to have two charts there at all. If you just eliminate the left column and put the 'Top 4 50%', 'Top 10 80%' and 'Rest of the World' labels right on the stacked chart on the right you get the same data with a simpler chart. Also, I don't understand the 'stylized flag coloring' of that chart - are you saying that the colors are attempting to match the countries' flags? If so, it is too subtle. You'd do better to include a small image of each flag in the bar. Or have I missed something?

Thanks for an intersting article.


Bob: Yes, agree with you on the bar chart.
For the second chart, I am trying to solve the problem of highlighting the main message. On any chart (pie, stacked bar) with country-level details, the reader's attention is immediately on the countries, not the aggregate groups of countries. The two sides could be overlapped on an interactive chart, in which the reader mouses over the aggregate groups to reveal the country details. I want to design a chart in which the reader first pays attention to Top 4, Top 10, and then look at individual countries. Any ideas?


I agree with Bob on both points.

I like the idea of the second chart, but I find it a little confusing to see both side by side. I think if I were to try to create the second chart, I would do something like this:


This is a quick Excel version, and could use some tweaks and cleanup, but is the general idea. I wouldn't fight against the idea of adding flag icons inside the boxes for each country, but I don't think it's necessary either.

(I also did my version of the pie/bar while I was at it: https://imgur.com/WSPeqfs )


JLB: I like your version of the chart, and think that using colors for the Top 4 and Top 10 solves the problem. I'd prefer to keep the building blocks as horizontal 10% slices rather than using treemaps.


Kaiser - thanks. I had tried it is a single stacked bar, and didn't like it, but what you're saying is more like a unit chart. Maybe I'll give that a try.


As a unit chart, just for fun:



JLB: Thanks! I think this is a bit better than the treemap. One other thing I did was to break free from the precision imposed by standard block sizes, so I allowed the blocks to be slightly uneven in lengths. South Korea, Mexico and Russia all had roughly 10% share - that's the message. So I had them in three blocks, with slightly rugged right edges, instead of wrapping around the extra lengths. The next messages are: Turkey plus Japan is roughly 10%. Then, Taiwan, Germany and India form the next 10%. To me, allowing errors of a few percentage points yields talking points that are 10 times clearer.
