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/

Inizia eseguendo il JSFiddle collegato e leggendo l’entry point Plotly.animate, quindi esamina come le API di base dei grafici go.Bar, go.Pie e go.Scatter espongono le opzioni di animazione. Prima dell’implementazione, definisci il comportamento e i criteri di accettazione del flag opt-in per questi tipi di grafico; l’issue non indica file o test.
