Took me a very very long time to make sense of the chart.

Watts/kg up, minutes over which that power output was sustained to the right.

White points are Vingegaard climbs in the past, yellow points are Vingegaard climbs in 2022, pink points are other cyclists.

The yellow and white curves are just trend lines? They seem to just be distracting.

And Riis's climb of Hautacam in 1996 is "off the charts" by being very high and to the right.
