Power BI and Tableau are used for graphic visualization of the information gleaned from data. It can be in the form of various charts like bar, line, ribbon, pie, donut, ribbon, gauge, map etc. Charts and tables are arranged in dashboards along with text and filters. A report can have several dashboards that tell a story about your data. Reports can be presented as is or uploaded to servers for online presentation. Reports can also be exported as a PowerPoint file for presentation at business meetings. They can also be embedded in client websites. Reports remain interactive in all formats except PowerPoint. This means that we can change the values of the filters and see the report update immediately. Power BI and Tableau use their own scripting languages to perform calculations and data cleansing.
