Iceland and maps have a long tradition in the history of cartography. From the first maps of the country in the 16th century (including works from cartographers such as Ortelius and Mercator, also featuring some nice sea monsters) to today’s advanced digital mappings of Iceland’s diverse natural environment (such as this innovative mapping of water in Iceland or this quite beautiful representation of contour lines), Iceland never really had a lack of quite good cartographic works. Much less covered than the natural environment are the social landscapes of the country, such as this just recently updated version of a gridded population cartogram of the country where each grid cell is proportional to the number of people living in that area:
Renewable energy is defined as ‘energy from a source that is not depleted’. Main sources include biomass, hydropower, wind, biofuels, solar, heat pumps, biogas, geothermal, and marine (such as tidal power). Data by the International Energy Agency sees the share of renewable energy in global power generation at 22 per cent in 2013, with an estimated increase to 26 per cent by 2020 as a result of supportive policies by a large number of governments.
Tropical cyclonic systems are generally referred to as tropical storms. They are better known by their regional names, such as hurricanes in the Caribbean and North America, or typhoons in parts of Asia. They form near the equator over larger bodies of warm waters that evaporate from the ocean surface and fuel these emerging storm systems. Their strong winds and heavy rainfalls frequently become part of our news as they often put large numbers of human livelihoods at risk.
Recent studies show that the number of tropical cyclones (as well as tropical cyclone intensity) over the past decades has increased. Tracks of tropical storms collected over a longer period can indicate where such storms occur most frequently. The records used in this issue’s visualisation covers data from 1945 to 2008.
Alternative ways of presenting the results of the Olympics has become more popular in recent years. Google – as other media outlets – did alternative medal counts allowing you to rank the medals not by their absolute numbers, but by other indicators such as population, GDP, or even more quirky themes such as fans or healthy eating.

The Rio Olympics, the first on the South American continent, ended after a total of 972 medals were handed out in 306 events. Approximately 11500 athletes competed in 28 sports for a total of 306 gold, 307 silver and 359 bronze medals. The following cartogram series sums up the most successful of all participating countries by resizing each country according to the number of medals going to athletes from there:
Wine is produced commercially in more than 70 countries, three of which account for almost half of the world’s production: France, Italy and Spain. What else does a closer look at the world of wine tell us?
The geography of wine – the product obtained exclusively from the total or partial fermentation of fresh grapes – can be viewed both from the perspective of producers or consumers. Continue reading
