Support to apply styles to node title

[CaptSadaf]

Thanks for awesome library!

Is there any way to apply styles to nodes title as in the below attached image? We can append text to node and format the string but no styles?
node.append("text").text(()=>{return "string"})

@CaptSadaf you can attach a div based on your current mouse pointer position using .on('mouseover', () => { /* append div with custom html with styles */})
