Expected some interface to an Altair computer and blinking lights. People don't care anymore how they name their projects. :-(

Altair here is a play on the underlying library called Vega. They're both stars in the "Summer Triangle" https://en.wikipedia.org/wiki/Summer_Triangle

Plotly Express (https://plotly.express/) is a new high-level wrapper on top of Plotly.py which gives a similar API to Altair in a lot of ways.

Under the hood it works the same way: Plotly.py generates JSON figure descriptions which are passed to Plotly.js for rendering.

The whole thing is, of course, free and open-source and well-documented :)

People don't call their programs IBM or Apple.

How about a JavaScript library to extract the second to last character of a string and call in Commodore Amiga 3000?

Excellent visualizations! Could you share the code used to create your last sample chart?

This example gives you the main structure: https://altair-viz.github.io/gallery/ranged_dot_plot.html. Let me know if you need the specific code for that visualization, happy to share it.

The problem with all these nice new visualization libraries for Python, is that they all (at least the shinny nice ones) fail totally short when it comes to do B&W graphics for journal publications. Things like filling patterns, line patterns etc, are mostly missing. I still use Matplotlib and I can make it look beautiful and exactly how I want... it's just a lot more work to get the shinny bits.

It is a great package. Two disadvantages are that the interfacte is not very pythonic and that there is no interactivity.
