In Power BI, which element is used for visual representation of data?

Visualizations are the key element in Power BI that serves for the visual representation of data. They provide an intuitive way to present complex information, enabling users to understand data insights quickly and effectively. Visualizations transform raw data into graphical formats such as charts, graphs, maps, and tables, facilitating easier interpretation and analysis.

The other options serve different purposes within the context of Power BI. The Data Model refers to the structure that defines how data is organized and related. While it is crucial for managing and relating your data, it does not visually represent that data. Data Sources are the origins from which Power BI retrieves data, such as databases, online services, or files. Fields are the specific columns of data in a dataset that can be used in visualizations; however, they require visual elements to present that information visibly. Therefore, visualizations are distinctly focused on the presentation aspect of data analysis in Power BI.
