Please show the graphs with all the cooling measures that took place

I am unable to display visual graphs directly, but I can describe the timeline and major Singapore property cooling measures since the 1990s. These measures are typically shown on trend graphs plotting residential price indices, where drops or stabilization often correspond with policy implementation dates.

Key cooling measures usually highlighted on such graphs include:

- 1996: First major round of restrictions on speculative buying and tightening of housing loans.

- 2009–2013: Multiple rounds introducing Seller’s Stamp Duty (SSD), Additional Buyer’s Stamp Duty (ABSD), and the Total Debt Servicing Ratio (TDSR). Notably, TDSR came in June 2013, capping loans at 60% of income for new purchases.

- 2018: Raised ABSD rates and minimum down payment for second property buyers, implemented in July 2018.

- December 2021: Further increase of ABSD rates for non-residents, entities, and second (and subsequent) property buyers.

- September 2022: Introduced a 15-month wait-out period for private home owners buying HDB resale flats, aiming to moderate demand in the public market.

- April 2023: Another round of ABSD hikes for both Singaporeans and foreigners to curb investment demand in private residential properties.

Each of these measures is typically plotted on property price index graphs, with annotations marking the introduction date. These events often correspond with:
- Temporary slowdowns, stabilization, or moderation in price growth.
- Shifts in transaction volumes for both HDB and private markets.
