From where does a visualization pull its data?

A visualization primarily pulls its data from a data source. This data source can be a specific set of data, such as a database, a report, a data mart, or even external data feeds. The data source serves as the fundamental building block that provides the necessary information for creating various visualizations, allowing users to analyze trends, patterns, and insights.

In this context, other options may involve aspects related to data manipulation or extraction but do not represent the direct origin of the data for visualizations. Report builders are tools that help create reports but do not serve as data sources for visualizations themselves. Database connectors facilitate the connection to a database but do not directly deliver data to visualizations. The analytics engine processes data analytics tasks but again does not directly serve as the data source. Thus, identifying the data source as the correct answer reflects an understanding of where visualizations retrieve their data from in a structured analytics environment.
