What makes a person happy? No other theme has more studies than happiness. People are interested on what happiness is depended on. For a bunch of people, money is the key for happiness. For other people a long and healthy life is everything they need to have a happy life.
In order to get to the bottom of this question, I create a data visualization on the topic happiness with various factors that could lead to a happy life or it said that these facts make a life livable.

The basis is build up by the data of the Happy Planet Index.

"The Happy Planet Index measures what matters: sustainable wellbeing for all. It tells us how well nations are doing at achieving long, happy, sustainable lives."

The Happy Planet Index (HPI) is calculated from the wellbeing, ave-rage life expectancy, inequality of outcomes and ecological footprint of an country/nation. The result is the average happiness of the people in the country. The HPI ranking goes from one to nine, while 1 is the best and nine is the worst.


This data visualization shows the average happiness distribution all over the world related to the factors prosperty, average life expectancy and happy life years.

The concept is build up on two levels. The navigation - level forms the basis. Here it is possible to select between different types of views (Continent view, world view and regions view). With two compari-sons levels (average life expectancy - prosperity and average life expectancy - happy life years) the user can see, how specific factors can lead or miss - lead to achieving happiness.

(comparison levels)

The selection on the navigation level is done by clicking in the desired region. If you click in the background, you are able to go one level back. Going one level back is given by clicking in the background.

Animations clarify the change between the different levels.


The initial shape which is used for the visual representation of the different data sets, is the square. Various visual parameters, such as size, position and opacity, offer different possibilities of comparisons. The HPI is defined by color. The color code of the ranking is mode by a nine-step gradation over the colors green to blue to purple.
