Power BI Desktop (formerly Power BI Designer) is the tool that allows us to create Power BI visualizations. It is a stand-alone Windows Desktop application (a Mac version has been submitted to the Ideas section of the Power BI forums – see here).
To install the tool, go to https://powerbi.microsoft.com/en-us/desktop/ and download the latest application.
Once installed, access the application through the Windows Start menu:
Opening the desktop, you will be able to connect to different data sources to start building reports.
The desktop application checks for updates, and you will find yourself downloading updates regularly (which shows Microsoft’s commitment to keeping the product up to date and leading edge).
I will go into more detail on how to use the desktop in other posts.
