I couldn't find information on grabbing information from a specific map view. For example as done in Zillow. I'd need to have a box outside the map showing information from the pointers only shown in current time. When the user changes the view displaying less / more pointers, the info box would update in real time accordingly.
Could someone help me finding examples or how-tos on how to implement this?
You will want to use the map view change event to fire an event to get the data for the current map view. This can be done by taking the bounding box of the viewable map and getting the data that falls within this area from your database. Once this information is sent back to the client dynamically update your box that is outside your map and the data on your map.
