Ola Rosling, product manager on the search team, said the global focus of the data should make Google's visualization capabilities more meaningful to Google users outside the U.S. "I'm from Sweden and I had a hard time getting Swedish people excited about local unemployment rates in the U.S.," he said.
Rosling said that Google relies on user search volume to determine which data sets to render in chart form. "We see a lot of people desperately trying to find out information about the data in news articles," he said.
Visualizing data, he said, leads to happier users. "It's definitely improving the search experience for users," he said. "Users basically express their frustration by refining queries back and forth." There's less of that, he suggested, when search results include graphs.
