Project Introduction and Motivation

With the continually rising prices of car prices in Singapore and the increasing polarisation of incomes in the country, our group intends to discover what have been the changes in the market demand for cars. Going deeper into the market, we will also show how the tastes for car brands have waxed and waned over the years. Demand for cars like Datsun and Supra have disappeared off the roads, while Fords and Audis have taken their places. Are Singaporeans starting to prefer more American and German cars than before? From the visualisations, we hope our users will be able to clearly segment the car market in Singapore and target the right group of buyers for their businesses.

Target Audience

We aim to deliver a highly interactive web application that allows someone to easily navigate between a large amount of time-series data and geographical data.

Our intended audience are:

1. Car dealers to make better forecast for car stock
2. Prospective car buyers
3. Potential Car Suppliers wanting to enter the Singapore vehicle market

Objectives

In this project, we will be focusing on the following:

• To discover the trend of registered cars and the COE for different brands across time
• To help consumers discover current and future COE trends for different cars categories (A & B)
• Trends in Singapore car market by brand (geography, market segmentation)

Dataset

Dataset/Source	Data Attribute	Rationale of Usage
New Registration of Cars (Jan 2002 to Aug 2017) https://insights-ceicdata-com.libproxy.smu.edu.sg/Untitled-insight/myseries	Car brands Month and Year Number of registered cars	This dataset will be used to understand the current trend of the car market in Singapore
COE Price Data https://insights-ceicdata-com.libproxy.smu.edu.sg/Untitled-insight/myseries	Month Bidding Round Vehicles Class Quota Amount No. of Successful Bids Premium Amount (S$)	This dataset will be used to track the car demand of the consumers and their willingness to buy a car in Singapore
Car Prices by Model https://www.onemotoring.com.sg/content/onemotoring/en /lta_information_guidelines/buy_a_new_vehicle/car_cost/_jcr_cont ent/main_par/download/file.res/Car_Cost_Update.pdf	Serial No. Make Model Bidding Round Total Basic Cost (S$) Total Basic Cost (With COE) (S$) Average Selling Price by Authorised Dealer (S$) Average Selling Price by Authorised Dealer (With COE) (S$)	This dataset will be used to track the car demand of the consumers and their willingness to buy a car in Singapore

Background Survey of Related Works

Related Works	What We Can Learn
An interactive treemap indicating importers' revenue of different countries Source: http://atlas.media.mit.edu/en/profile/hs92/8708/	Colour indicates different continents, eg. Asia, Europe, North America etc. Size indicates proportion of sales amount in the market Hovering over the area indicates more detailed information Provides a high level view of our data and displaying the item details at the same time. It allows us to see patterns quickly when our eyes visually aggregate rectangles in the same group.
An analysis of the trend of coe in a bar chart representation Source: http://coe.sgcharts.com/	Use line graph to compare the changes of COE prices over the years. Bar chart indicates the different COE prices over time
Sunburst Diagram to visualize hierarchies in no. of registered cars by brand Source: https://accessanalytic.com.au/the-top-3-new-charts-in-excel-2016/	Provides an overview of the breakdown of data in categories hierarchically. Colour can be used to highlight hierarchical groupings or specific categories. Shows car brand proportion accurately

Proposal of StoryBoard

Proposed Visualization	Explanation
Sunburst Diagram	This type of visualisation shows hierarchy through a series of rings, that are sliced for each category node. Each ring corresponds to a level in the hierarchy, with the central circle representing the root node and the hierarchy moving outwards from it. Colour can be used to highlight hierarchal groupings or specific categories. We believe that a sunburst diagram would be effective as we would be able to visualise the number of cars breaking down from region to country to car brand. We would be using chart since it is easy to implement and interactive. These are some variations of the sunburst that we are considering too.
Treemap with Geographic Heatmap	Treemaps are used to display hierarchical data. Treemaps are economical in that they can be used within a limited space and yet display a large number of items simultaneously. We chose to use a tree map, because it would give an overview of the amount spent on different car brands, car brands of similar regions would be grouped with same colour. The cars would be grouped by continent. When the cursor hovers over the continent, the geographic heatmap will be displayed to show the country distribution for that continent.
Radial Stacked Barchart	We may want to effectively compare the COE prices. As there would be many years and months of COE, a radial stackbar chart will allow the prices to be presented in a single view and not across the screen. This is a non traditional take of the bar chart.

Technical Challenges

Technical Challenges	Mitigation Plan
Obtaining datasets	Go through databases provided by the library Enlist help from Professor Kam for CIEC access to data
Acquiring Data, Data Cleaning	Plan the cleaning process and work closely to clean and analyse all data sources
Using d3.js and Highchart to display the visualisations which we want	Attend D3 Programming Workshop Designated time and roles on learning on D3 and HighCharts Libraries & Technical Tools Peer Learning
Unfamiliarity in Implementing Interactivity and Animation Tools/Techniques in Visualization App	Develop a Storyboard Different specialisation on Interactivity/Animation Techniques Referred to existing data visualisations for implementation
