Altair is another somewhat more pythonic library based on the grammar of graphics. It's also great for interactive visualizations.
Thanks for doing the math on that! That's really useful information. I was under the impression that flying was a bigger issue than those numbers suggest--I hadn't ever bothered to do the calculation myself.
For the record, I didn't actually downvote you--just wanted to share why I suspect others did. I agree with your full reasoning and didn't mean to imply you thought that was the only significant difference. I mostly agree with what habryka is saying, though.
I'm sympathetic to the point you're making - practice is a very different thing from reading. But, how you wrote it reads as overly harsh.
EDIT: to be more specific, calling that lumping "ridiculous" and saying nothing at all could be concluded from the poll were both far harsher than warranted IMO
I clicked the button :( But, I clicked it because the first thing I saw on the page was a big shiny button and hadn't been on the site in a few day and didn't know what it would do. I would not have entered codes if I'd had them. Maybe give a more noticeable warning next to the button next time? Maybe something like "Warning, pressing this button will..." in red text.
Just commenting to say thanks for sharing this! I'm a statistician currently dipping more into python/ML (mostly an R background) with a casual interest in trading and this looks like a great set of material to work through while learning.
Said this in a separate comment but wanted to add here that there is a python library wrapper for this which is pretty nice also: https://altair-viz.github.io/getting_started/overview.html
