Adventure Map Question

This is probably a stupid question but I just bought Waterdeep Dragon Heist. The adventure comes with a 'poster' that is a map of waterdeep. Is there any way to view it online in such a way that you can zoom in? When I access it though the adventure module it opens in a pop up window that doesn't seem to allow for zoom and with my cruddy eyesight I can't make out a single thing that is supposedly marked on the map. It is just too dense. Which of course makes it utterly useless to me. 
What am I missing?

Thanks. I was wondering if I would have to do it that way or if there were a specific place in Beyond to view and work with maps.
