Tableau- representing world data

Disclaimer: While I don't have the factual verification of the data, the example shown here is for academic-illustration purpose only.

The participating countries : 216
No. of variables for analysis(Parameters): 45

The mode of representation of graphs is what need to be analysed. I am giving my own mode of visualisation and understanding of the dataset.

Sample visualisation  of data:

Top 30 countries in birth and death rate.

2. Top countries in gas and oil consumption

3.Other parameter like debt, infrastructure, GDP 

GDP:  Size shows % of Total GDP. The marks are labeled by Country. The data is filtered on sum of GDP, which ranges from1,500,000 to 11,750,000,000,000. The view is filtered on % of Total GDP, which from 2.00% to 17.46% .

4. How is the life expectancy and the mortality rate?
