Synopsis
In this competitive global environment, the ability to explore visual representation of business data interactively and to detect meaningful patterns, trends and exceptions from these data are increasingly becoming an important skill for data analysts and business practitioners. Drawing from research and practice on Data Visualisation, Human-Computer Interaction, Data Analytics, Data Mining and Usability Engineering, this course aims to share with you how visual analytics techniques can be used to interact with data from various sources and formats, explore relationship, detect the expected and discover the unexpected without having to deal with complex statistical formulas and programming.
The goals of this course are:
- To share with you the principles, best practices and methods of visual analytics
- To provide you hands-on experiences in using commercial-off-the-shelf visual analytics software and programming tools to design visual analytics applications
Learning Objectives
Upon successful completion of the course, students will be able to:
- Understand the basic concepts, theories and methodologies of visual analytics.

Basic Modules
This course comprises ten integrated components as shown below:
Prerequisites
There are no prerequisites for the class. However, students taking this course must be willing to learn R programming framework. For students who are new to R, you are encouraged to consult the following resources prior to the lesson starts:
- Garrett Grolemund & Hadley Wickham (2020) R for Data Science. This book is highly recommended to anybody who are interested to understand how to do Modern Data Science by using tidyverse principles and methods.
- 王敏杰 数据科学中的 R 语言.
You don't have to finish reading either one of them before lesson starts. Take your time, review them from time to time. You will find yourself learning something new each time you revisit the book.
Course Assessment
The assessment of this course consists of four major components, namely:
- In-class Hands-on exercise and class participation,
- DataViz Makeover
- Individual assignments,
- Visual Analytics Project.
There will be no mid-term test or final examination for this course.
In-class Exercise and Class Participation
A strict requirement for each class meeting is to complete the assigned readings and to try out the hands-on exercises before coming to class. Readings will be provided from the textbook on technical information and from provided documents and articles on business applications of Visual Analytics. Students are required to review the recommended readings and class exercises before coming to class. Without preparation, the learning and discussions would not be as meaningful. Student sharing of insights from readings and hands-on exercises of assigned materials in class participation will form a large part of the learning in this course.
During lesson, students are required to complete a series of hands-on exercises using either Tableau or R. In general, these exercises are guided if Tableau is used. For R programming session, hands-on guides will be shared on RPubs before lesson starts. By the end of each lesson, students are required to upload their in-class exercise onto eLearn for reviewing. The exercises will be briefly reviewed after collection. Students will be given 10 points for correctly completing the exercise, 7-9 points for partially completed and correct work, and 0 points if absent. Up to 100 points can be accumulated during the term.
DataViz Makeover
Each fortnight, I will post one or two data visualisation and you are required to critic, suggest ways for improvement and rework the data visualisation. Maybe you retell the story more effectively, or find a new story in the data. I am curious to see the different approaches you all take.
The purpose of the makeover is to improve on the original visualisation. Focus on what works, what doesn’t work, why those things don’t work, and how you made it better. You should try stick to the fields in the data set provided and improve upon the original visualisation. However, if supplementing the data helps you tell a better story, go for it!
The write-up of the DataViz Makeover must be in blogdown format. You are required to publish the write-up on netfily. If Tableau is used to complete the DataViz Makeover, students are require to upload their Tableau workbook onto Tableau Public.
All DataViz Makeover have to be completed by Friday before mid-night 11.59pm. Students are required to provide the URL links on eLearn (i.e. DataViz Makeover 1).
Individual Assignments
There is one assignment that is due throughout the term. The assignment must be completed using R. The write-up of the assignment must be in blogdown format. You are required to publish the write-up on netfily. Assignment due is to be uploaded into the course wiki strictly before the official due dates. Late work will be severely penalised. Students must check and confirm on Wiki the assignment due dates.
The assignment will be graded on a scale from 0 to 100. Scores of 70 and 80 are given when the assignment is essentially done completely and correctly. Scores 80 and 90 are reserved for complete and correct homework where extra initiative or innovation clearly sets the completed work above the simple, perfunctory and satisfactory completion of the mini-assignment.
Visual Analytics Project
The purpose of the project is to provide students first hand experience on collecting, processing and analysing large business data using real world data. A project may involve developing new methods or implementing visual analytics system to support analytic tasks in specific domains. Alternatively, a project may be in the form of application development by integrating analytical tools within a visual analytics environment. Students are encouraged to focus on research topics that are relevant to their field of study. It should address a concrete visual analytics problem and should propose a novel and creative solution.
