Visualization of the Week: Every meteorite strike mapped

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.

Visualization of the Week: Profits vs Super Bowl ad expense

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.”
