Waterfall Chart Creations

I have a table with Region and Population as attribute. Where the population of India (Country) is bifurcated into tagged region named as East, West, North and South, and untagged region is named as Other. Other = India - sum(East,West,North,South); so as per the value Other = 2500.

I need to create the model in PowerBI. I tried using the Query Editor but struggle to obtain the result as mention below in Waterfall chart. Help will be appreciated.
