I should have known if the apps free, you’re the product. Duolingo appears to harvest the most data compared to other language learning apps.

The fact that the lines and the labels are not aligned makes this visualization very weird.

The whole chart is a disaster.
The dots are aligned with the lines, not the row labels.
The app names, which should be headers, aren’t aligned with there own columns. I’m guessing that was to fit an aspect ratio for ads?
The color coding fades from red to blue… there are a morbillion other colors, why not make them distinct?
Not to mention how deceptive the actual content seems to be.
