Hi, I am new to d3 and I wondering if anyone can assist me with creating a tooltip which displays the airport locations. I have been able to plot the locations onto the app but unable to create the tooltip. Any help would be gladly appreciated.

Hello, tooltips are notoriously difficult to make in SVG. I’ve used tippy.js a few times to display complex (HTML) contents: Hello, Tippy.js / Fil / Observable.

Another (cheaper/easier) option is to use native tooltips, by adding a <title> element to the svg mark.
