CPT111-2324 Coursework 3 Task Sheet
Overview
Coursework 3 (CW3) is the final coursework component of the course this semester. It contributes to 30% of your final marks.
You will apply the object-oriented principles, file processing techniques, data structures, and graphics concepts you have learned throughout the semester to visualize data from input files. Additionally, you will create a video presentation to demonstrate your problem-solving skills and understanding of object-oriented principles.
You are required to submit the following files: Java code, a Word and PDF report, an ethics quiz, an MP4 video, and a PowerPoint (PPT) presentation used in the video.

University Lateness Policy
Report and video files are allowed to have late submission with penalty for max 5 days. There will be no late code or ethics quiz submissions since feedback is given by the automatic grader or quiz. This is consistent to University lateness policy on not having late submission period for assessment with feedback.
Outline
The rest of the task sheet will describe the visualization tools, the detailed specification of the tasks, and the deliverables you have to submit.
Coursework 3 – Data Visualization
Data visualization involves the use of graphical elements and structures to represent and communicate data patterns, relationships, and insights. Diagrams are visual representations that can simplify complex data, making it easier for viewers to understand and analyze information. Data visualization using diagrams serves several purposes such as Data Exploration, Data Presentation, and Pattern Recognition.
You must choose one type of diagrams in this coursework:
1. Bar Charts, a simple visualization for a standard mark (max 70 marks).
2. Sankey Diagrams, a more complicated visualization for a higher mark (max 100 marks).
For the remainder of this task sheet, we will explain how the Sankey Diagram will be graded, with a maximum coursework score of 100 marks. The marks for bar graphs will be adjusted proportionally, with a maximum coursework score of 70 marks.
Bar Charts
A bar chart is a graphical representation used in data visualization to display categorical data with rectangular bars. Each bar's length or height corresponds to the value it represents, making it easy to compare and analyze data across different categories. Bar charts are widely used in various fields to convey information effectively, such as the amount of investment, sales and profit over the years.
A sample of Bar Charts from Wikimedia Commons
To create a bar chart from a data file, you will need to specify the categories, setup the chart's axes, and customize its appearance with titles or legends.
Sankey Diagrams
A Sankey diagram is a diagram that represents the flow of quantities or values within a system. It uses arrows or lines to represent the flow of these quantities. The width of the arrows or lines is proportional to the quantity being transferred, to visualize
the relative magnitudes within the system. This diagram can also be adapted to show how a whole quantity or a source value is divided into different categories.
A sample of Sankey Diagram from sankeymatic.com
For example, in the diagram above,a budget of $2,025 is divided among categories such as taxes, housing, food, transportation, healthcare, and other necessities.
Data Set
Several datasets will be given as examples.
Each data set is stored in a text file, with the first line serving as the title of the
diagram and the second line as label of the source. Following these two lines, there area variable number of additional lines, each containing the name of a category along with the corresponding value. For example:
|
example1.txt |
example2.txt |
|
Year 1 |
Spending Plan |
|
Resources |
Budget |
|
Invest 4300 |
Taxes 500 |
|
Sales 2400 |
Housing 450 |
|
Profit 2200 |
Food 310 Transportation 205 Health Care 400 Other Necessities 160 |
Specification and Deliverables
In this section, you will find the expected details regarding your implementation and the files that you are required to submit.
Specification
Your implementation must satisfy the following specification:
1. You may submit multiple files, but your main file must be named by your
student ID followed by an underscore and the diagram of your choice.
For example:
2223344_barcharts.java
2225566_sankeydiagrams.java
2. You must only use libraries taught in this course, such as File, FileReader,
BufferedReader, Scanner, List, ArrayList, Map, HashMap, JavaFX.
You are not allowed to use other libraries, which may instantly produce the
diagram or perform other direct operations.
3. The name of the text file should be passed to the constructor of your class responsible for reading the file. Your program should open the text file and
read the data into the instance variables, before visualizing the data.
Alternatively, for additional feature, the name of the file can be input into
your graphical interface or other creative solutions.
4. You must handle the exceptions that may be thrown.
5. You must consider good code writing practice and code readability. Please
refer to the rubric in the following subsection.
Report Requirements
Create a report satisfying the following criteria:
1. The purpose of your report is to explain your code, algorithms, file/error
handling, display features, and OOP design in well-detailed manner.
2. Your report must consist of exactly 7 Chapters:
Chapter 1 – Object-oriented Principles
(you may add subchapters here)
Chapter 2 - Diagram Display Algorithm
Chapter 3 - Display while Resizing Algorithm
Chapter 4 - Additional Features
Chapter 5 - File Handling
Chapter 6 - Exception Handling
Chapter 7 - My Java Code
3. You must include all your code in Chapter 7.
4. Write your report using Word with the following setting:
Font Calibri, Font Size 12, Line Spacing 1.5, Normal Margins.
