- Emphasize design considerations for ensuring usability and accessibility.
Evaluation Criteria
The submission will be assessed based on its comprehensive layout and clarity, logical progression from research to design, and a deep understanding of Tableau's interactive features. The DOC file should reflect a coherent vision, using visuals (like diagrams) if needed, and must detail how the dashboard will effectively communicate the intended data stories. This task should involve about 30 to 35 hours of work and demonstrate a solid grasp of planning for interactive visualization.
Objective
This assignment challenges students to delve deeper into advanced visualization techniques that go beyond basic charts and graphs. Focus is placed on creating compelling narratives using advanced Tableau features such as calculated fields, advanced chart types, and dynamic storytelling. The task builds upon previous work by integrating the strategic plan, cleaned data, and dashboard designs into a more sophisticated visualization project that communicates trends and insights effectively in the beauty and wellness domain.
Expected Deliverables
- A DOC file detailing advanced visualization strategies and techniques.

- Descriptions of potential pitfalls, methods to overcome them, and step-by-step processes used to implement the advanced techniques.
Key Steps
- Identify advanced Tableau features and techniques that could benefit a data story in the beauty and wellness sector.
- Create a mapping of these features to specific data insights and narrative components.
- Detail the process for applying calculated fields, parameter controls, and custom scripts (if relevant) in Tableau.
- Write a narrative that illustrates the journey from raw data to an interactive, advanced visualization story.
- Discuss how these features improve user engagement and insight discovery.
Evaluation Criteria
Submissions will be evaluated on technical depth, clarity of advanced techniques, and the ability to describe why these methods enhance the overall data narrative. The DOC file should be well-structured, demonstrating creative and analytical thinking with a focus on precision. Candidates should ensure that the description is comprehensive, well-supported by examples or analogies, and corresponds to approximately 30 to 35 hours of dedicated effort.
Objective
This task centers on evaluating and optimizing the performance of data visualizations within Tableau. Students will learn to critically assess the effectiveness of their visualizations, considering both technical performance and the story impact in the beauty and wellness context. The goal is to refine visualization designs, identify inefficiencies, and propose improvements that ensure clarity, accessibility, and responsiveness.
