There is no data. The article links to the Cascend twitter page. There hasn’t been a new tweet since 10/29/2020 (almost 4 months) so there is nothing to back the graphs there. If you go to Cascend’s actual website, their example research and media pages have nothing newer than 2019.

My guess is someone found an old data research company and just put their name on a graph thinking people would believe it’s real.
