We are using d3.js tree (d3.tree()) to render org chart visualization. It is very similar to https://observablehq.com/@julienreszka/d3-v5-org-chart

I want to display small popup over the node on click/mouseover of some button. e.g. clicking on person image display small popup with some more actions. So user can click on any of the link in popup.

Is there any recommended approach to achieve it in D3js?
