Perhaps it’s the HAL 9000 from 2001: A Space Odyssey, or maybe it’s chess Grandmaster Garry Kasparov losing to IBM’s Deep Blue supercomputer.

Some 1,300 years ago, Chinese astronomers recorded the position of the stars and the shapes of the constellations. The Dunhuang star maps are the oldest preserved atlas of the sky: More than 500 years ago, the residents of the Marshall Islands learned to navigate the surrounding waters by canoe in the daytime—without the aid of stars.

Feed: Featured Posts - DataViz Author: Andrei Macsin Guest blog post by Chris Atwood Recently, I rediscovered a TED Talk by David McCandless, a data journalist, called “The beauty of data visualization.” It’s a great reminder of how charts (though scary to many) can help you tell an actionable story about a topic in a way that bullet points alone usually cannot. If you have not seen the talk, I recommend you take a look for some inspiration about visualizing big ideas. In any social media report you make for the brass, there are several types of data charts to help ... Read More
