Tableau Dashboard Enhancement

I need a Tableau dashboard cleaned up and enhanced. The data and logic are already built in, but it needs validation and design improvements to make it presentable.

Requirements:
- Validate data accuracy, calculation logic, and filter functionality.
- Update color scheme, restructure layout, and add visual elements like graphs and charts.
- Enhance overall design for better data visualization.

Ideal Skills and Experience:
- Expertise in Tableau
- Strong background in data validation
- Proficiency in design and layout restructuring
- Experience in creating visually appealing dashboards
