Interesting data visualizations from GE…don’t seem to be that useful though…

Interesting project for visualizing live data…

The rising tide of electronic data presents tremendous opportunities and challenges for journalists. Never before has so much information been publicly available, often in structured formats that are suited to electronic analysis. Based on the increasing volume and pace of data availability, it is easy to imagine a time not far off when data reporting becomes a part of every journalist’s job. So what then, are the skills that will be necessary for journalists to tell stories from — and with — data?

Geoff McGhee interviewed people who are pioneering data visualization in various fields to produce this documentary on the emerging art of data stories.

David McCandless turns complex data sets (like worldwide military spending, media buzz, Facebook status updates) into beautiful, simple diagrams that tease out unseen patterns and connections. Good design, he suggests, is the best way to navigate information glut — and it may just change the way we see the world.

David McCandless makes infographics — simple, elegant ways to see information that might be too complex or too big, small, abstract or scattered to otherwise be grasped. In his new book, Information Is Beautiful (in the US, it’s being called The Visual Miscellaneum), McCandless and his cadre of info designers take a spin through the world of visualized data, from hard stats on politics and climate to daffy but no less important trends in pop music.

Thanks to advances in sensing, networking, and data management, our society is producing digital information at an astonishing rate. According to one estimate, in 2010 alone we will generate 1,200 exabytes—60 million times the content of the Library of Congress. Within this deluge of data lies a wealth of valuable information on how we conduct our businesses, governments, and personal lives. To put the information to good use, we must find ways to explore, relate, and communicate the data meaningfully.

The goal of visualization is to aid our understanding of data by leveraging the human visual system’s highly tuned ability to see patterns, spot trends, and identify outliers. Well-designed visual representations can replace cognitive calculations with simple perceptual inferences and improve comprehension, memory, and decision making. By making data more accessible and appealing, visual representations may also help engage more diverse audiences in exploration and analysis. The challenge is to create effective and engaging visualizations that are appropriate to the data.
