CPT111-2324 Resit CW Task Sheet

Overview

Resit Coursework (Resit CW) is the only component of the course for resit students. It contributes to 100% 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.

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.

Resit Coursework – 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. Pie Charts, a simple visualization for a standard mark (max 70 marks).

2. Spider Charts, a  more complicated visualization for a higher mark (max 100 marks).

For the remainder of this task sheet, we will explain how the Flow Diagram will be graded, with a maximum coursework score of 100 marks. The marks for pie charts will be adjusted proportionally, with a maximum coursework score of 70 marks.

Pie Charts

A pie chart is a circular graphical representation of data, divided into slices to depict the proportions. Each slice of the pie chart represents a specific category. Pie charts are particularly useful for displaying data with distinct categories and showing the relationship between each category and the whole. They are often used to visualize data such as market share, for example market share of web search engines below.

A sample of Pie Charts from Wikimedia Commons

To create a pie chart from a data file, you will need to specify the categories, setup the size of each slice correspond to the proportion or percentage of the whole, and customize its appearance with titles or legends.

Spider Charts

A Spider Chart is a data visualization diagram that displays data on a circular grid.

This chart type is particularly useful for comparing multiple different categories. In a   Spider Chart, each category is represented by an axis radiating from the center of the circle. Data values for each category are plotted along these axes and connected to create a polygon, making it easy to compare the values of different categories.

Spider Charts are effective for showing patterns, similarities, and differences in data across categories, making them valuable in fields such as performance analysis.

A sample of Spider Charts from exceljet.net

For example, in the chart above, the performance review of a particular subject is shown across six different categories.

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 chart. Following the line, there area variable number of additional lines, each containing the name of a category along with the corresponding value. For example:

example1.txt

Web Search Engines Market Share Google 66

Yahoo! Search 16

Bing 13 Ask 3

AOL 2

example2.txt

Performance Review Summary Technical Skill 3

Experience 3

Accomplishments 3 Personality 5

Sense of humor 5 Work ethic 4

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 chart of your choice.

For example:

2223344_piecharts.java

2225566_spidercharts.java

2.   You must only use libraries taught in this course, such as File, FileReader, BufferedReader, List, ArrayList, Map, HashMap, JavaFX libraries.

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 exceptional cases / exceptions that may be thrown.
