Polymaps Interactive - NatGeoMag Population The World of Seven Billion The map shows population density; the brightest points are the highest densities. Each country is colored according to its average annual gross national income per capita, using categories established by the World Bank (see key below). Some nations— like economic powerhouses China and India—have an especially wide range of incomes. madewulf/MigrationsMap.net Choropleth Choropleth maps visualize geographic distributions using a color encoding. This example shows U.S. unemployment density by county, as of 2009. An Albers equal-area projection preserves the accuracy of the representation. Choropleth design invented by Charles Dupin . Colors by Cynthia Brewer . Data from the Bureau of Labor Statistics , by way of Nathan Yau . Source Code
How Did We Get to 7 Billion People So Fast? I love the cool infographic video from NPR. 7 Billion: How Did We Get So Big So Fast? is a video that uses colored liquids to visualize the population rates of the differen continents. High birth rates mean fast liquid pouring in, slower death rates slow down the liquid dripping out of the bottom. The U.N. estimates that the world’s population will pass the 7 billion mark on Monday. Found on FlowingData
peoplemovin - A visualization of migration flows vis4.net 7B people & you: What's your number? Sources: All population data are based on estimates by the UN Population Division and all calculations provided by the UN Population Fund. The remaining data are from other sections of the UN, the Global Footprint Network and the International Telecommunications Union. Want to find out more? Visit the UN Population Fund's detailed population calculator, 7 billion and me. Notes on the data: Only birth dates after 1910 can be accommodated and only countries with populations of more than 100,000 people are included. Three country groupings - developed, developing and least developed - featured in the conclusions are those referenced by the UN for assessing the Millennium Development Goals.

InstantAtlas Dencity Dencity maps population density using circles of various size and hue. Larger, darker circles show areas with fewer people, while smaller, brighter circles highlight crowded cities. Representing denser areas with smaller circles results in additional geographic detail where there are more people, while sparsely populated areas are more vaguely defined. Read more about how Dencity was made. HTML5: Flow map of internal migration in England & Wales At the start of this year, I wrote a brief post on how we’ve been looking closely at the emergence of HTML5 as a visualisation platform. This week, we’ve published the first fruit of those labours – an interactive flow map of internal migration data for England & Wales: The aim here was to really stretch the technology and give it a tough visualisation challenge to see what it’s capable of. The underlying data used in the map contains over 60,000 migration flows – yet we have still managed to produce an interactive application that will run on an iPhone. I will aim to write some more details later on the development process and the good and bad experiences of transitioning from a platform like Flash. Like this: Like Loading...
