Create the examples’ gallery for dataframe lib

[zakurdaevm]

Summary
We have a very nice examples ’ gallery for our Kandy Library.

You can find it here: https://kotlin.github.io/kandy/examples.html

It suggests choosing the type of chart (which you can see visually) which you want to render, and you will be able to copy the code and paste in the kotlin notebook and run it.

From my point of view - it's very convenience especially for new users (like as smooth onboarding).

The idea-suggestion is to create something similar for dataframe library (maybe with some main/popular code structures).

Hi! I like this idea and we've been thinking about it before. However, dataframes are not as visual as plots, so it may still be hard to look for what you need as a user.

We did try to include some tables describing the process of operations (like here) or something more colorful (like here) though that has been more difficult to reproduce for other places. But as you can see, it's not immediately clear from the tables which operation is being performed.

Maybe it is still possible to do it and we just haven't found the right way yet. Do you have an example of a dataframe gallery from another library perhaps?
