Visualising Age Distribution of Motor Vehicles

Today's newspaper has an ad on our Government web sites, and one of them caught my attention. That's data.gov.sg. The data from LTA on Age Distribution of Motor Vehicles is the one that I want to visualise using gnuplot

The animated image clearly showed that more new cars were introduced in 2006. After that the new car business gradually dropped to a record low in 2011. This definitely tally with the COE (Certificate of Entitlement) price and quota.

I am still trying to get hold of the COE data so that I can combine all these information in a single plot. It would be really nice if the data from data.gov.sg is given in its raw format.

Here is my gnuplot code to generate the animated gif file
