The venerable Wired magazine has surely gone too far with this flight of fancy! Consider:
- The zig-zagging lines streaming across the map
- The redundant white dots, each of equal size, contradicting the black dots, with size proportional to prevalence
- The inexplicable use of 00, 01, 02, ...
- The use of a taller column for human cases, when tallied, amounting to about 1/20 the number for bird cases
- The inclusion of Australia (with zero cases) while excluding the Americas (also zero cases)
- Ordering the countries neither by bird nor human cases but by convenience of placement on the map
As with a previous example, the map adds nothing to the data except for providing a lesson in geography. We prefer a parallel bar chart, shown on the right. Here, the continents are given different colors. In an unusual move, I chose different scales for each side as I am more interested in the distribution among countries, rather than the relative prevalence of bird/human cases.
