Geo Map Charts

Geo maps allow you to visualize data that contains geographical coordinates (latitude and longitude). Using coordinates allows you to place visual data elements more precisely on map charts.

Create a Geo Map Chart

A dataset with geographical location data, such as U.S. states, can be overlaid on a U.S. map. The bubbles representing a measure appear centered on the state areas. If the locations are tied to particular areas in those states, coordinates can be used to locate the bubbles more accurately.

For example, with airline data tied to particular airports, use airport latitude and longitude coordinates to visualize the data at each airport's actual location. The dataset could look like the following:

In the lens, click and then select the Geo Map chart type.
To select the map type in the chart properties, click .
The map type depends on the region that you want to show in the map. For example, if your flights are only in the Unitied States, select US States.
In the Locations field, select the location field that determines where to add bubbles. For example, select the Airport field.
In the Latitude and Longitude field, add two measures: the first contains average latitude coordinates and the second contains average longitude coordinates.

Tip If you’re adding measures in a SAQL query, add the latitude and longitude measures first, and then any other measures.
In the Bubble Size field, add a measure that determines the bubble size, such as sum of flights.
In the Bubble Color field, add a measure that determines the color, such as sum of passengers.
To make additional changes, such as setting the colors of the geo map chart bubbles, set the chart properties in the Formatting panel.
