Back when I did a lot of data stuff I used ggplot in R because it seemed to be popular, but I was just copy/pasting examples. Then one day I finally started to "get it" and actually read the manual. Learning the grammar of graphics was like a super power. I got to the point I could open pretty much anything people sent me and visualise it in a matter of seconds.

Although I've used Python professionally a lot more than R, I still felt like R was better at this. Somehow opening files in Python always feels a bit more "heavy". I don't really know why, though.
