In Power BI, which component is primarily used to visualize data?

Power BI Desktop is primarily used to visualize data because it is the main application where users can create reports and dashboards. It provides a rich environment for data transformation, modeling, and visualization. Within Power BI Desktop, users can drag and drop fields onto the report canvas, apply various visualizations such as charts, tables, and maps, and customize the aesthetics of these visuals. This interactive platform facilitates the exploration of data, making it easier for analysts to communicate insights effectively.

While Power BI Mobile and Power BI Service allow for viewing and interacting with reports and dashboards created in Power BI Desktop, their functionalities are built around the visualizations that originate from the Desktop application. Power BI Mobile focuses on on-the-go access to these visuals, and Power BI Service serves as a cloud-based platform for sharing and collaborating on reports. Power BI Dataflow, on the other hand, is more concerned with data preparation and ETL (extract, transform, load) processes rather than visualization, meaning it serves a different purpose in the data analysis workflow.
