ENTRIES TAGGED "visualization"
A visualization shows credit and terminal transactions the week before and the week during Mobile World Congress 2012.
Mobile World Congress is going on this week in Barcelona. CartoDB and BBVA teamed up to visualize the economic impact one of the world’s largest tech conferences has on its host city. The team took the credit card transaction data from Mobile World Congress 2012, separated by visitors and locals, and compared it to transactions the week before the conference in a running timeline visualization:
Vizzuality and CartoDB co-founder Javier de la Torre created a heatmap of meteorite impacts and produced a how-to video of the map's creation.
The meteorite that struck Chelyabinsk, Russia, last week — the largest reported since 1908, when a meteor hit Tunguska, Siberia — prompted the Guardian’s Datablog team to pull together data from the Meteorological Society, identifying all known meteorite impacts on Earth, some dating back to 2300 B.C. The initial map the team created with the data seems to be down, but their map inspired Vizzuality and CartoDB co-founder Javier de la Torre to produce a heat map using the same data, which Datablog editor Simon Rogers also highlights at The Guardian.
Two visualizations look at how commuters get to and from work.
The team at Quartz compares 3.5 hours of advertiser profits to the nearly $4 million Super Bowl ad price tag. Were the ads worth it?
Commercials have long been a highlight of the Super Bowl (if you missed any, the Verge grabbed the Hulu compilation), but how much do the advertising companies profit from the notoriously expensive ad spots?
Ritchie King at Quartz pulled together a chart to provide context. King reports that ads this year sold for an average of $3.7 to $3.8 million, but as King explains and the chart shows, that dollar figure is a mere “pittance” for the advertising companies. “In fact,” King notes, “some of them make almost as much in profits in an average 3.5 hours — roughly the time it takes to air the Super Bowl itself.”
Using WHO data, The Guardian Data Blog team pulled together a world map of annual pollution exposure.
The latest reports of severe smog blanketing Beijing inspired The Guardian Data Blog team to dip into World Heath Organization data and design a world map of annual pollution exposure by city. Data Blog researcher Ami Sedghi writes:
“The World Health Organisation (WHO) warns that exposure to particulate matter increases the risk of many chronic and acute respiratory conditions in children and adults. The WHO air quality guidelines indicate that by reducing particulate matter (PM10) pollution from 70 to 20 micrograms per cubic metre, air quality related deaths can be reduced by around 15%.”
The Australian Bureau of Meteorology adds new colors to forecast maps to accommodate rising high temps topping 129 degrees Fahrenheit.
Australia’s Bureau of Meteorology recently had to update its interactive weather forecasting chart to add new colors. Peter Hannam explains at The Sydney Morning Herald that the previous temperature range topped out at 50 degrees Celsius (122 degrees Fahrenheit) to accommodate forecasted high temperatures. Now, they’ve had to add two new colors, dark purple and bright pink, to represent temperatures up to 54 degrees Celsius (129.2 degrees Fahrenheit). Hannam captured a forecast map for 5 p.m. January 14 that required the new deep purple color.
An interactive chart showing equivalent inflation-adjusted incomes and effective federal tax rates for the past century.
Prompted by Warren Buffett’s appeal to establish a minimum tax on the wealthy and the “fiscal cliff” negotiations in Congress, Ritchie King designed an interactive chart showing historical effective federal tax rates (federal taxes paid divided by taxable income) based on inflation-adjusted 2012 income.
ASU researchers find the science behind the Lakers' 2010 championship.
Had the Lakers consulted with Arizona State University (ASU) researchers Jennifer Fewell and Dieter Armbruster, they might have gone a different way after firing coach Mike Brown. Nonetheless, current Lakers coach Mike D’Antoni may be wise to consult Fewell and Armbruster’s work. The duo led a team at ASU that used a network analysis model to analyze basketball plays — they applied the technique to the 2010 NBA playoffs to help explain the results.
According to their published research paper, “[t]he study involved more than a thousand ball movements and typically more than one hundred sequences or paths for each team” in the playoffs, which provided enough data to enable them to treat the game as a network.
Researchers at BombSight.org have developed an interactive map visualizing the London Blitz.
A team of researchers and developers at BombSight.org has put together an interactive map showing every bomb dropped during the London Blitz of World War II, between October 7, 1940, and June 6, 1941. The bird’s eye view of the map (shown below), though inaccessible for deriving any detailed data, shows the sheer volume of destruction wreaked upon the city in those eight months.
The real value in this visualization is found when you drill down to specific areas. The dots turn into bomb icons that can be clicked to bring up additional information about that particular devastation, including a “read more” link that brings up a page with related images in that area and related stories from people who were nearby at the time of that bomb drop:
