Making a Family Tree inside a sheet [Pendragon 6th]

Hi, I've recently worked on a revised version of the Thierry MATTRAY Pendragon 5th ed. Sheet, updating it to 6th edition. Since family are an important part of Pendragon's system, I was wondering if there's a way to make one tab for the sheet where you can actually create a Family Tree, maybe with some customizable tooltips, giving more information when you hover on the family memeber's name. Is there a way to create that? Maybe with repeating section?

I mean, maybe? You'd have to explain exactly what it should show.

there is , however it's a lot of complexity and will have some pretty severe limitations.

Well, actually I'm looking from something really simple, and not complex, something like that: It should show only the names, perhaps with an icon next to them that displays a tooltip with some additional information. However, it should extend downwards rather than to the right like this one to avoid making the sheet too wide. But it should have the ability to add both descendants and ancestors. The player character text area could be indicated by a different color compared to the rest of the family members, maybe a different background. Oh, most important, there should be a way to show if the family member is dead or alive (strikethrough? Different color?).

That's a good example: Pendragon extended family tree

While it'd be possible to do a limited family tree implementation, something that could handle the full example in your second image isn't possible.

Then even a limited version will be fine. Any advice on how to set up the HTML and CSS?
