A previous script uses lines-interval plots (fn:1) to visualize data for energy use and population. Plotting with rectangles is more direct for this type of visualization. Accumulating population numbers gives a feel unequal distribution of energy, a lot more people live in countries below the mean than above the mean.

With more time to play with these visualizations I'd like to see if it's easier to label more countries on the plot that accumulates population along the y-axis.

Here's proof that the code for this plot worked in DrRacket:

DrRacket is good for visualizations. Emacs helps me do the preparatory thinking and editing, but adjusting plot details is fun in DrRacket. The .csv data used for this post's visualization is below the code.

Using the same wikipedia data as a previous script and post (fn:1), this is a reproduction of another of Hiroaki Koide's小出裕章の graphs. It was good brain training and attention strengthening to figure out how to do this with Racket Plot.

Reproducible research techniques with DrRacket could contribute to a good, exploratory education. Learners can hack the script, make lists of countries to label, adjust the sizes of the plot and create something that they feel is worth printing out to thinking about...
