Visualisation of HDB Property Sales in Geylang from 2010

Ok since the Tableau embed code won't work, click here to see the visualisation.


After completing the Tableau Essential Training course on Lynda, I wanted to build a portfolio of work on Tableau. Since many friends were looking to buy property, why not see if I could help them narrow down:

  1. Where to buy
  2. How much to offer

Also, to give them the flexibility of filtering the size, age and location of the houses.

Artificially-imposed data restrictions

1. 4-room flats only

As most friends are young couples, the assumption is that a large resale 4-room flat would suffice for their needs (and budget) for now. I also wanted to seperate 4 and 5-room flats for now to reduce visual clutter.

2. Data from 2010 onwards

Though data is available as far back as 1990, I assumed that looking 8 years back of data is more than sufficient.

3. 6-floor units and above

The assumption is that the friends would prefer units on higher floors.

4. Geylang only

Being as "Eastie", I am more familiar with houses in this area. Hence, I chose to look at this area first to get a functional visualisation up, before later expanding to other areas.


Honestly, this is still a work in progress. I still want to move some data around before seeing if any trends emerge. That being said, a surprising discovery was made on another batch of property data, which will not be revealed for now :). This post is to make me accountable for a proper analysis soon.
