A link visual enhances your applications by accessing external sources of information. These sources may be either static URL addresses, or dynamic — results of searches to which you pass a name of a variable used in the dataset.
The following steps demonstrate how to create a new link visual for dataset World Life Expectancy [data source samples.world_life_expectancy]. In this exercise, we will pass the variable country to the Wikipedia site.
Start a new visual based on dataset World Life Expectancy [data source samples.world_life_expectancy]; see Creating Visuals.
In the visuals menu, find and click link (row 2, column 4).
Note that the shelves of the visual changed. The only visible shelf is URL.
