Visibility tool allows you to control displayed objects onto a map. In the Visibility panel, you have several options to show and hide all types of objects - markers and any type of visualization. 

You can display (or hide) an entire group of markers with just a single click. Markers can represent restaurants, branches, ATMs - whatever is most relevant to your data. You can even toggle the display of individual markers within the group simply by clicking on eye icon on the right. You can also use "Only", "Invert" or "Select all" tools. 

You can also hide (and display) the primary visualization. It gives you an almost clear map for context. It is possible to control type of visualisation currently used in the view.

The "Keep filtered objects in the map" toggle allows you to display or hide objects (markers, areas, dots or lines) that doesn't carry any data under current settings of filters, global date or selected object with data relation to other objects. 

When you turn this option on the "filtered" objects switch to suppressed mode. Markers get black, other objects get gray.
