What is Power BI?

Microsoft’s tool for turning data into interactive reports and dashboards.

In plain English

Power BI connects to many data sources, lets you clean and model the data, and then build visuals that people can filter and explore. Reports are shared through the Power BI service. It is a common tool for the visualisation and reporting part of an analyst’s job.

Example

A sales dashboard where managers click a region and every chart on the page updates.
