Point Layer
The Point Layer draws dots on the map corresponding to latitude/longitude coordinates.
One of the most commonly used layers, the Point Layer can be leveraged in a variety of use cases where coordinates are available. The layer is one Studio's most configurable, with options to base the color, radius, and stroke on an attribute column.
