Every dot is the date since when an apartment is hosted (“host_since” column in the data), with the name of the owner. Dots are not removed. Location will be from 0-450 feet (150 metres) of the actual address (anonymized by Airbnb).
Sometimes the same name appears at different locations. However, there is nothing wrong with the animation or your computer.
