Where once infographics were a bit of a niche specialism, in recent times they seemed to have gatecrashed the mainstream and you frequently see someone on Twitter drooling over the latest info-tastic offering. So it is with perfect timing Sandra Rendgen has produced a spectacular new book looking at this phenomenon – how infographics have developed, why they’re useful and how they work. There’s more than 400 examples in the book too, which proves Albert Einstein’s maxim: “If you can’t explain it simply, you don’t understand it well enough.” We spoke to her to find out more…

US Wind Patterns

Nicolas Garcia Belmonte, author of the JavaScript InfoVis Toolkit, mapped 72 hours of weather data from 1,200 stations across the country.

Gathering the data from the National Weather Service was pretty interesting, I didn’t know USA had so many weather stations! The visualization shows wind direction encoded in line angles, wind speed encoded in line lengths and disk radius, and temperature encoded in hue.

Press play, and watch it glow. You can also easily switch between symbols: discs with lines, lines only, or filled circles.

"Our ability to generate information now far exceeds our capacity to understand it. Finding patterns and making meaningful connections inside complex data networks has emerged as one of the biggest challenges of the twenty-first century. In recent years, designers, researchers, and scientists have begun employing an innovative mix of colors, symbols, graphics, algorithms, and interactivity to clarify, and often beautify, the clutter." And look! Even Jeremy Deller's been invited to the party continue

Mining Your Logs - Gaining Insight Through Visualization

Google Tech Talk (more info below) March 30, 2011 Presented by Raffael Marty. ABSTRACT In this two part presentation we will explore log analysis and log visualization. We will have a look at the history of log analysis; where log analysis stands today, what tools are available to process logs, what is working today, and more importantly, what is not working in log analysis. What will the future bring? Do our current approaches hold up under future requirements? We will discuss a number of issues and will try to figure out how we can address them. By looking at various log analysis challenges, we will explore how visualization can help address a number of them; keeping in mind that log visualization is not just a science, but also an art. We will apply a security lens to look at a number of use-cases in the area of security visualization. From there we will discuss what else is needed in the area of visualization, where the challenges lie, and where we should continue putting our research and development efforts. Speaker Info: Raffael Marty is COO and co-founder of Loggly Inc., a San Francisco based SaaS company, providing a logging as a service platform. Raffy is an expert and author in the areas of data analysis and visualization. His interests span anything related to information security, big data analysis, and information visualization.
