Bro, this video is better than altair docs kkkk great job ... I came here because I'm refactoring an streamlit app and was not remebering all those little things (kinda asking my self why I didn't pick an easier lib to do the charts, and altair docs is kinda hard to read) ... but after the video you could remeber me all the fundamentals, and remeber also that Altair is a great library!!!

Man you deserve more subscribers!
How is Altair compared to other interactive dataviz libraries like Bokeh and Plotly?

I'm using both Bokeh and Plotly, looks like Altair is in the middle ground.
In terms of the ease of use: Plotly > Altair > Bokeh.
In terms of professional looking output: Bokeh > Altair > Plotly.

Is there a way to drag points/bars around and have it run a function accordingly?

What keyboard is that it sounds incredible

Hard to see, can you use higher resolution and a white background? But make the text not to small

[eyvind]

Hey man! I was wondering how i can get the difference in value between data points.
I can get the difference between one point and the one prior to it, but how can i get the difference between a datapoint and another, say 20 places ahead of it?

Pendapatnya bang soal Polars vs Pandas?

Man, i love your video, but idk, the small windows for looking into web pages, maybe is better for the viewer if you tab to full screen when you look for something. I'm using 27'' 1440p and that still small!.
