Autumn 2023: Assignment 1

Relational Data Visualisation

(Assignment deadline: Sunday 23/04/2023, 11:59pm on vUWS)

Assignment Details

For this assignment, you are required to identify and develop one (or more) visualisation(s) for    relational data sets (such as graphs, networks, and trees as presented in lecture notes in week 3 and week 4) using existing tools, software or your own development using available libraries.  You might use the sample datasets at the tutorials as well as the provided visualisation techniques. Alternatively, you are encouraged to search and use other visualisation tools and/or   datasets in the literature. Based on the visualisation(s), you can explore to find insight, patterns,   ir(regularity) and interesting properties from the visualisation.

You are also required to write a report (approximately 1000 words but no limit) on the following aspects:

•   Brief technical details of the used visualisation method(s),

•   Discussion on the advantage and disadvantages of the visualisation method(s) in comparison with other methods in the literature. Can the visualisation method(s) be used effectively for large relational data sets, and why?

•   Discussion on the analysis results and findings on the datasets,

•   Discussion on other aspects, literature review of related work and your critical thinking on the visualisation(s).

Note: images (asfigures) are essential and should be included in the report to illustrate the visualisations, results andfindings. A report with more than 1000 words is also acceptable.

Marking criteria for the assignment includes

•  Development of visualisations for relational data (60%). You might use existing tools

(e.g. tree visualisations, Gephi, Cytoscape, etc.), existing software libraries (e.g. D3.js) or write your own program in R, Python, Java or any other programming languages. The marking will be based on how well the visualisation methods present the relational data.  Interaction should also be included in the visualisation.

•  A report on the technical description of the visualisation, analysis results and other aspects (40%)

Deliverables

Students must individually complete the visualisation(s) and the report. 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 a consistent and complete referencing style) are expected. The data and source code (if have) should also be submitted on vUWS.

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.

I hereby certify that no part of this assignment/product has been copiedfrom any other students work orfrom any other source except where due acknowledgement is made in the assignment.

No part of this assignment/product has been written/producedfor me by another person except where such collaboration has been authorised by the subject lecturer/tutor concerned.

Submission

The declaration, visualisation program(s) and datasets, and the report should be submitted via vUWS before the deadline for marking purposes. In the Turnitin submission system, the report (preferably in PDF or MS Word) is submitted separately together with a compressed zip file     containing all supporting program(s), data sets or other supporting works. Please ensure the file names include your student id. A submission that does not follow the format is not acceptable. No hard copy of the work and email submission is acceptable.

Important Note

Please note: it is not advisable to copy the materials from illustrating samples, your friend’s   works, works from previous years, or other sources. In addition to Turnitin checking, we may run a cross-check of the reports to detect plagiarism. Failure to comply with plagiarism avoidance may lead to misconduct with a serious penalty.
