support vertical parallel coordinates

[anders-kiaer]

We are using the parallel coordinates plot from plotly.js in a Dash app. The number of variables/parameters is quite large, which makes it necessary to scroll it horizontally for the user. In our use case, vertical scrolling would be more natural.

It might be that it already is possible to "flip" the parallel coordinates plot, and specify categorical axis as vertical, but we haven't been able to find such a setting.

Good idea.
I added a feature label.
BTW here is a quick prototype using CSS.

Hey @gvwilson, this is also a feature we need for skrub! We would be glad if this could be brought to P2 😅 Also, we might be able to contribute if it can help solve this issue.

Hi @Vincent-Maladiere - unfortunately we're not going to be able to get to this in the next couple of cycles, but if you and/or your colleagues would like to put together a PR I can prioritize review - please let me know. Thanks - @gvwilson
