While making the chart on fertility rates (link), I came across a problem that pops up quite often, and is ignored by most software programs.
Here is an earlier version of the chart I later discarded:
Compare this to the version I published in the blog post:
Aside from adding the chart title, there is one major change. I removed the empty plots from the grid. This is a visualization trick that should be called adding by subtracting. The empty scaffolding on the first chart increases our cognitive load without yielding any benefit. The whitespace brings out the message that only countries in Asia and Africa have fertility rates above 5.0.
This is a small edit. But small edits accumulate and deliver a big impact. Bear this in mind the next time you make a chart.
(1) You'd have to use a lower-level coding language to execute this small edit. Most software programs are quite rigid when it comes to making small-multiples (facet) charts.
(2) If there is a next iteration, I'd reverse the Asia and Oceania rows.
