Newsweek's "The World's Best Countries" [newsweek.com] feature presents an interactive ranking of the globe's nations according to metrics from areas such as health, economy and the quality of life. Essentially, it consists of a series of linked plots, where individual countries can be selected and compared to each other. In addition, income, population or country groups can be highlighted in the plots.
Although, overall, the information density is a bit overwhelming, there are some nice details about the visualization that make it worth mentioning:
- Interaction. The simple switch-on-switch-off paradigm makes it effortless to explore this large and interconnected data set.
- Persistency. As you progress in selecting countries, the last, previously selected countries remains highlighted as a comparison point. This makes it very easy to compare countries with each other.
- Trust. Data sources and methodology are explained in detail, something that is often missing from visualizations.
Overall, an easy and enjoyable way to dig through this rich data set - how does your country fare?
