Visual Analytics (COMP2026)
Autumn 2025: Assignment 2 (Group of Two or One)
Multidimensional Data Visualisation
(Assignment deadline: Sunday 08th of June 11:59pm on vUWS)
Assignment Details
For this assignment, you are required to identify and develop one (or more) visualisation(s) for the given multidimensional data set using available software and/or programming platform(s), (e.g. Tableau, Power BI, TabuVis, R, Python, etc.). Based on the visualisations, you can explore to find insight, patterns, ir(regularity) and interesting properties from the visualisation. Note that you may need to clean and pre-process the data before using them in the visualisation tools or programs.
Upon your visualisations and analyses, you are also required to write a report with 1000 words (note: your report can be longer than 1000 words if necessary) on the following aspects:
• Discussion on the advantages and the disadvantages ofthe visualisation method(s) in comparison with other methods in literature. Can the visualisation method(s) be used effectively for large data multidimensional data sets and why? Which other analysis techniques could be helpful to support the visualisation in big data analysis? Such as in the data processing, automated analysis, etc.
• Discussion on the visualisation methods (including geographic visualisation, time series, charts and other advanced visualisation methods), analysis results and findings on the data sets, such as: i) How does the obesity situation among different educational levels via illustrations with geographic visualisations? ii) How do obesity or smoking situations change over time via illustrations with time series and/or geographic visualisations? iii) How do the different health indicators or a specific health indicator, such as smoking, differ among different countries? iv) What are the trends ofthe different health indicators or a specific health indicator, such as obesity, among different countries? And more.
• Discussion on other aspects, literature review of related work and your critical thinking on the visualisation(s).
Note: images (as figures) are essential and should be included in the report to illustrate the visualisations, results and findings.
Marking criteria for the assignment includes
• Development of satisfactorily visualisation(s) for multi-dimensional data (60%). The marking will be based on how well the visualisation methods present the multidimensional data. Interaction should also be included in the visualisation.
• A report on the technical description of the visualisation, analysis results and other aspects (40%)
• Students in the same group (will receive the same score in normal circumstance.
Deliverables
Students must individually or in a group complete the visualisation(s) and the report. Each group has maximum 2 students. The report should be typed and submitted online through vUWS as a Word or pdf file. A high standard of professional English and neat logical structure (including consistent and complete referencing style) is expected.
Declaration
You are required to submit a declaration with the following claim (in a text file or world file).
DECLARATION
I hold a copy of this assignment that I can produce if the original is lost or damaged.

No part of this assignment/product has been written/produced for me by another person except where such collaboration has been authorised by the subject lecturer/tutor concerned.
Submission
Together with the report document, the declaration, visualisation program(s) and data sets, and the report should be submitted via vUWS (with Turnitin) before the deadline for marking purpose. All these files should be zipped into one file with your student id as the zipped file name. Submission that does not follow the formats is not acceptable (i.e. Doc or PDF format for the report document, and ZIP file for source codes and others). No hard copy of the work and email submission is acceptable. For group submission, only one student will need to submit the assignment report to avoid 100% Turnitin similarity, and clearly indicate the second group member in the report. Other group members will submit the Zip file only which should also include the report file for recording purpose.
