Cartograms - It's a new World out there...

Couple of days back, I had an idea to create World Map based on variables such as Population,GDP, Per capita health care expenditure etc.
I was excited...I thought I found a new visualization model...I dreamt of  ...name.....fame...new contribution to world of visualization....
Then, I did a little search on Google. I understood such visualizations are in vogue and are called Cartograms....
At the end, I cursed that someone copied my idea even before I could conceive it...
However, I have come to terms with it....

Let's see what these Cartograms are..
For those who are familiar with Bubble Charts, understanding Cartogram is easy...
Cartograms are simply maps of the world where in size of an entity like a country or a Continent is proportional to the size of  the variable being depicted.
Let me give you an example.

If we were to create a Cartogram of the world based on the Area of each country, you will see the Map exactly like the world map we see... Like the one on the right side...



If we were to create a cartogram of the world based on the Population of each Country, you will see the map like this.on the left side...

You will see the world from a different view point....
