HTML/Svg Content over treemap boxes

[HolyOne]

Hello, I am trying to add responsive html/svg contents to treemap boxes. Like a background picture and a title+link

It does not seem possible with plotly. so I tried css approach but there is no way to select the .slice.cursor-pointer or the underlying surface because they dont have the data-id s associated with the underlying data.

Can you add some functionality to add id's to them so we can style with css?
Or can you provide a way to add html content on them?

I also tried to add some customdata, it either dont work or the documentation is missing on how to grab those custom data. I mean I expected customdata to add data-something to the html tags of boxes.

I think treemap should provide a render() function that sends width, height, id, label of the content to a function, and use its return value to paint its contents.
