You have to set a new height (you can calculate new height based on the content, using . getBoundingClientRect function ) and rerender the graph

So

when user clicks the button • Calculate new height of the node based on the new content and save it somewhere, preferably assign the data of the node itself, call it expandedHeight or something • rerender the graph and provide new height in the following way: chart.nodeHeight(d=>d.expandedHeight?d.expandedHeight:defaultHeight).render()
