# Growth Domestic Products of Nations : Bubble-Force Chart

Bubble Chart is easy to understand : it is a chart describing data using bubbles / circle. The radius of the bubble – circle usually reperesents the measurement of the value of data.

Note : if the controls aren’t working, try use the ‘Data By’ control first, it should go back to normal. Sorry about the bug.

Data By

As a rule of thumb : the smaller the bubble – circle radius, the lesser the data value, the greater the bubble, the larger the value.

This visualization is describing the Growth Domestic Products of various nations around the globe.

Hint :  you can drag the bubbles.

#### UNDERSTANDING GROWTH DOMESTIC PRODUCT

According to wiki :

Gross domestic product (GDP) is a monetary measure of the market value of all final goods and services produced in a period (quarterly or yearly) or income.

In other words, if we calculate the sum of all prices of all things sold in a country, goods and services alike, within an entire year (or quarterly), then we will have calculated the  GDP of a nation.

Still quoting from the same source :

Nominal GDP estimates are commonly used to determine the economic performance of a whole country or region, and to make international comparisons. Nominal GDP per capita does not, however, reflect differences in the cost of living and the inflation rates of the countries; therefore using a basis of GDP per capita at purchasing power parity (PPP) is arguably more useful when comparing differences in living standards between nations.

In other words :

• There are two ‘ways/formulas’ to calculate GDP of a nation, which, in turn, resulted in two ‘types’ of calculated GDP : Nominal GDP per capita and GDP per capita at purchasing power parity (PPP). Hence forth we will call them as GDP – PPP and GDP – Nominal.
• GDP – Nominal is measured in US\$ (United States Dollar), while GDP – PPP is measured in Int\$ (International Dollar).

You surely now understand that the bubble radius represent the value of GDP, bubbles with larger radius represent nations with greater GDP value.  Apart from the radius,  bubbles also have colors.

The bubble color represents various regions / continent where a country is located. You can use the legend located on the right of the bubbles as reference to understand which color represents which region.

If you would like to view GDP of a single continent or region, just click on the legend circle represents whichever region you interested in (for example : click on the ‘Europe’ legend circle), and the bubbles will arrange themshelves accordingly..

You can, however, opt to use the color to describe the ‘level’ of nations GDP, just click on the ‘by GDP – Categorized’ option of the ‘Color’ control group. The lighter the bubble color, the smaller the GDP, the darker the color, the greater the GDP.

There are 5 pre-defined levels of GDP, represented by five legend circles : ‘0 to 1000’, ‘above 1000 to 10,000′ all the way up to’ above 5 millions’, of millions of US\$ or Int\$. Similiar to ‘Color’ ‘by Region’ option, just click on any of the legend circle to plot/choose your selected GDP level.

The third and the last color option, ‘by GDP amount’  is similiar to the ‘by GDP – Categorized’ color option, only that your selected level is not pre-determined; you choose the minimum and maximum value of GDP level to be plotted using the slider control.

That all the basic you need to know, there are some I don’t explain, which i’m pretty sure you can unravel yourself by playing around with the controls below. Go ahead, do not hesitate to experiment with the controls…

Data source(s):

Note : the sources above only listed GDP values of countries, but no data of which country belong to which region/continent. I must took extra effort to googling and wiki-ing around for the region data, so i maybe made some mistakes about this.

For example : i’m not sure of wether i should include Iraq into ‘Asia’ or ‘Middle East’ region, so i just followed my hunch and include Iraq into ‘Asia’. If you see it wrong in regard of these ‘region classification’ of mine, please drop a comment.

Update (Monday, 9/18/2017) : Now with sort function! Just try the ‘Sort’ checkbox! 😛
