Project Description
I am looking for an experienced Tableau Public/Desktop expert (preferably with teaching, mentoring, or data visualization assessment experience) to review and grade 28 learner Tableau workbook submissions (.twbx files).

1. Time-series visualization
2. Forecasting analysis
3. Geographic map visualization
4. Calculated field using IF-ELSE logic
5. Animation over time
6. Dashboard development
7. Dashboard interactivity (filters/actions)
8. Dashboard layout and design
9. Business insights and recommendations
10. Dashboard interactivity evaluation
The complete exam instructions will be provided.
