In this prototype, information on who is attending is pulled from the database. Eventually I'd like the icons to display a message from those attending rather than simply their name(s).
Use the zooming ladder on the left of the map to zoom in on the map for a more fine-grained look at the map. You can double-click on a spot to center the map at that spot.
You can click on an entry in the table on the left to zoom/center the map on that guest. Once you've zoomed and centered, the map's zooming ladder can zoom out/in more. You can click on balloons on the map to see information as well.
