Deaths on Mount Everest plotted against year, altitude, and camp level: climbers vs sherpas (guides)

They took it from their own earlier article:
[https://www.bbc.co.uk/future/article/20151008-the-graveyard-in-the-clouds-everests-200-dead-bodies](https://www.bbc.co.uk/future/article/20151008-the-graveyard-in-the-clouds-everests-200-dead-bodies)

I wondered why one climber was highlighted and not mentioned in the article (Tsewang Paljor); it was because he was mentioned in the original article but not in the later article that borrowed the same graphic.

Also, the data is from 9 years ago.
