Heptathlon rankings with parallel coordinates

The Guardian covered the rankings for the women’s heptathlon, specifically how Nafissatou Thiam from Belgium pulled off a surprise gold.

The main chart is a variant of a parallel coordinates plot. However, the chart type, which is usually read left to right, is rotated for vertical reading, and instead of straight connecting lines, a path of right angles is used instead. Nice. [Thanks, Matthew]

Chart Type Used

Parallel Coordinates

Differing scales run alongside each other, sometimes showing relationships between multiple variables through connections. Can be tricky though.
