A bubble map uses a map as the background and shows the distribution of data in a country or region by using bubbles of different sizes. For example, you can use a bubble map to check the passenger flow of tourist attractions, or show the per capita income of different regions. This topic describes how to add data to a geo bubble chart and configure a style.
Prerequisites
A data dashboard is created. For more information, see Create a data dashboard.
