I like that the map shows past users (30+ hrs ago) and the circle size indicates how long ago they were on the site. It would also be nice to have a view that just shows current people who are on the site now, not ones who were on several hours ago.
Right… it shows the last 100 visits. Therefore the map is not really “real-time” It’s just a visual representation of the visitor log in a sense. It would be nice to have the map really be real-time, so once a visitor’s visit expires (based on the session timeout), they are not shown on the map.
