With regard to the Dataset, the process of “catch-up” in average income implies that less advanced economies should experience faster growth in output per capita, typically by adopting the practices of more advanced economies, notably as regards capital, technology and labour utilisation. While less developed countries may grow more rapidly at the beginning of the catching-up process, their economic growth rates are expected to decline over time as their income levels come closer to those of the more advanced countries.

For each country, the rate of “catch-up” vis-à-vis the United States is calculated as the difference between the average annual compounded growth rate of its GDP per capita level over the period and the average annual compounded growth rate of the United States’ GDP per capita level over the same period.

Comparisons of income and productivity levels for a particular year are derived from the time series of Gross Domestic Product (GDP), population, employment and hours worked of the OECD Productivity Database. For some countries, GDP and population data were also derived from Angus Maddison (2001), The World Economy: A Millennial Perspective, OECD Development Centre, OECD, Paris.

Calculations are based on GDP measures converted from national currencies to US dollars using 2006 Purchasing Power Parities.

Based on GDP data, converted to US dollars using 2006 PPPs (purchasing power parities). US = 100. This dataset can be found

For the visualisation, I tried to involved all techniques of previous assignments including mapping, interactivity and animation. Specifically, I drew circle with basic radius of each country’s income, then adding a slider to present the radius changing through the period from 1973 to 2006. Also a barchart has been inserted to show a clear comparison of income values among countries and can be interacted with the slider component, which means the comparisons can be provided from the barchart in each year of the period. I calculated screen position for every country to interact with the barchart I made. So if I select a random country from the boxlist, specific zooming would display then the country position would show in the window and others hidden. Also the country selected would be highlighted in the barchart.

As for the animation, I decided to use a toggle to trigger the slider to display automatically. The the circles in the map and barchart status will also alter along with the slider. The last thing I did is to clearly visualise the income value changing through the period of each country. In order to do that, I classified the comparison between the incomes the current year and the previous year I defined. If the income decreases from last year, then the circle would colored in green and display as a shrink ripple. On the contrary, if the income value growing from the year before, the circle would be a rolling out ripple in red.

From the interactivity and animation, a much better and clear understanding of the data set is be revealed. For example, in 1974, all the countries’ income are in red and shrink from previous year except Japan.
