Same thing that happened when the internet became a thing (or is still in process of happening in many cases).

The things we need to learn change, and shift to adapt to how the works works. You don't need to know the Dewey decimal system anymore, but you need to know how to find information and determine which is credible. You don't need to know how to write cursive anymore, but you do need to know how to present your ideas in a way that other people will be able to understand them.

What is this, a post on r/dataisbeautiful where the OP recognizes they messed up and attempts to correct it? This is amazing!

I applaud your willingness to improve, but I do have to say that even your updated graph still gives the impression at first glance that every single cou try has more police killings than homicides, though the updated version it only takes a few seconds of study to correct that vs a whole minute of searching to discover the axes had different units. A truly beautiful graph of this data would show at a glance that while police killings were much lower than homicides in all countries, some countries have a worse ratio than others. Something like a bar graph of police killings per homicde (or per 10 homicdes or whatever) would do this much better than a scatter plot, because in the scatter plot there's no really good way to scale the axes to give the correct visual representation of this particular dataset at first glance.
