Add intro animations to basic plotly charts

A lot of modern JS charting libraries support intro animations like these:

I love using Plotly as a Pythonista and would like to make it look modern and fancy like the other charting libraries.

Does plotly have intro animations out of the box? If not, would this be relatively simple for me to add as a contributor to plotly.js? I am pretty proficient with javascript and can help.

My thought was to add this to the basic charts like go.Bar go.Pie & go.Scatter with a flag like enable_intro_anims so users can enable/disable them as per their choice.

I asked cursor to give me some sample code for how this can be done, and it looks like Plotly.animate can achieve this!

Here's the code - https://jsfiddle.net/am6914fb/5/

Start by running the linked JSFiddle and reading the Plotly.animate entry point, then inspect how the basic go.Bar, go.Pie, and go.Scatter chart APIs expose animation options. Before implementation, define the opt-in flag's behavior and acceptance criteria for these chart types; the issue does not name files or tests.
