Map charts are commonly used to compare values and show categories across geographical
regions. Map charts are most beneficial when the data contains geographic information (countries,
regions, states, counties, postal codes, and so on).

Latitude
Select a variable to serve as the latitudinal value from the drop-down
list.
Group

menu.
Category
Select a column variable that you want to visualize.
Summary
Select a statistical summary function (the method that is used for summarizing each category).
Two types of statistical summary functions are
available. The distinction is important because it determines whether you need to specify a
Value variable.
Functions that do not require a value variable. Functions that do not
require a variable. All count and percentage statistics are in this category. These statistics are
available when the Value variable is not defined.
Functions that do require a value variable. Functions that do require
a Value variable. For example, the Mean function requires
a variable on which the mean is calculated. These statistics are available when the
Value variable is not defined.
Value
This field displays when a Summary function that requires a value
variable, is selected. Select a variable to serve as the value.
Click the Save visualization in the
project control. Select Create a new asset or Append
