DW Portfolio Bubble Chart (Dec 2018)

I created my very first portfolio Bubble Chart! :) 
*X-axis: Yield-on-price 
*Y-axis: Unrealised paper gain 
*Size of bubble is based on market value of the counter 
*Propnex is excluded as it has not given a full-year dividend yet

Overall patterns: 
- All counters have above 4% yield-on-price except RMG 
- All counters are in the green except NetLink Trust (as of 14 Dec) 
- Most counters are concentrated in the middle-right part of the chart

Outliers: 
- DBS, Suntec & MNACT are the ones closer to the desirable top-right quadrant of the chart
