PROBLEM & MOTIVATION

Problem
As a buyer looking for flats in matured estates, or Resale HDB flats, it can be difficult to make a decision on your dream home due to the lack of information in the market and the tools to make comparisons. This problem is amplified further by buyers' complete lack of knowledge to decide if a price is good compared to the market average.

Motivation
According to Ms. Christine Sun, head of research and consultancy at OrangeTee, demand for HDB resale flats has been strengthening. Our group feels that with the increasing demand for HDB resale flats and the lack of information and tools in this area, there is a strong need for us to address the issue.

BACKGROUND SURVEY OF RELATED WORK

In order for our group to design a new visualisation, it was important to us that we understand the current work out there in the field. This will enable us to make informed decisions on developing our own visualisations. We can also learn from the current visualisations to ensure that our own work adds value and to not repeat any mistakes made. Listed below are screenshots of visualisations and their learning points respectively.

Reference of Other Interactive Visualization	Learning Points
Title: Official HDB Map Services Image5 Source: https://services2.hdb.gov.sg/web/fi10/emap.html	This is an interactive visualisation by HDB that we can search and filter different regions This visualisation is quite messy as icons of all current HDB in a particular is shown, and the user might be confused to which house to pick from The advantage of this visualisation is being able to visualise the clustering of HDB flats in a particular region
Title: Visualising 30 years of HDB resale flat prices between 1990 - 2019 Source: https://www.reddit.com/r/singapore/comments/dubsyk/visualising_30_years_of_hdb_resale_flat_prices/	This is a bar chart graph to depict the resale flat prices in regions around Singapore One advantage of this visualisation is that it is arranged in descending order, which allows the users to identify quickly the highest price of the region One lesson can be learned here is that some bar charts are slightly different in colour. This is because of the high amount of regions in Singapore thereby causing more spectrum of colours but decrease the ability to differentiate one from the other
Title: Distribution of 4-Room HDB Resale Prices By Town Source: https://medium.com/@wojiefu/hdb-pusle-visualization-of-singapore-hdb-flat-resale-records-2e2fbedbee91	This is a animated visualisation of HDB resale prices on the map of Singapore, it is very effective in showing us the changes in number of occurrence of transactions being made at what frequency A disadvantage of this visualisation is that there is no legend or information to relate the colours of the points and the actual resale price A disadvantage of this visualisation is that there is no clear indication of which region belongs to which section in the geography map of Singapore. This leaves the user with the onus to understand the location in Singapore
