Hello Badillo, Irvin,
Thank you for reaching out to us on the Microsoft Q&A forum.
The database used in the "Introduction to visuals in Power BI" module may not always be provided directly in the materials. However, you can create your own dataset or use a similar one with comparable columns such as Country, Date, GEO, Manufacturer, etc.
These training modules are primarily designed for educational purposes, and some modules come with exercises that include Virtual Machine (VM) labs to help you practice and complete the tasks.
If you are still facing any issue, please let us know in the comments and where you are encountering this error along with the screenshot for reference. We are glad to help you.
