Hi, I am looking at this https://chandoo.org/wp/60-sports-in-six-charts/ and especially the first chart, the charts are avalible for download at the end of the page.

I have my data in the same way as in the link but I don't understand the different steps needed.
How can I replicate or create a similar chart?
