The Data Visualization Beginner’s Toolkit #2: Visualization Tools

The Data Visualization Beginner’s Toolkit #2: Visualization Tools
(Note: if you are new to this series, the DVBTK doesn’t teach you how to do visualization. Rather it is meant to help people find a less chaotic and more effective path towards the acquisition of the necessary skills to become a data visualization pro. To know more, make sure to read the introduction to the series first.) The DVBTK #1 introduced books and study material to make sure you acquire the right knowledge in the right order. Studying is the first step and there’s no level of practice that can substitute for it. That said, it is extremely important to realize that good visualization cannot happen without practice. But if you want to do visualization you need some tools right? Here is the guidance. And there is more to come! I felt you needed to know more about each tool, so I decided to interview (at least) one data visualization professional with proven and long-lasting experience with it. Golden Rules of Visualization Tools First of all you need some fundamental rules. Damn it!

Think Twice: How the Gut's "Second Brain" Influences Mood and Well-Being As Olympians go for the gold in Vancouver, even the steeliest are likely to experience that familiar feeling of "butterflies" in the stomach. Underlying this sensation is an often-overlooked network of neurons lining our guts that is so extensive some scientists have nicknamed it our "second brain". A deeper understanding of this mass of neural tissue, filled with important neurotransmitters, is revealing that it does much more than merely handle digestion or inflict the occasional nervous pang. The little brain in our innards, in connection with the big one in our skulls, partly determines our mental state and plays key roles in certain diseases throughout the body. Although its influence is far-reaching, the second brain is not the seat of any conscious thoughts or decision-making. This multitude of neurons in the enteric nervous system enables us to "feel" the inner world of our gut and its contents.

Tal Raviv — Being a Developer Makes You Valuable. Learning How to Market Makes You Dangerous Being a Developer Makes You Valuable. Learning How to Market Makes You Dangerous I love engineering, and not just because I’m a nerd. The best part of engineering isn’t the technical details or the particular science behind it, rather, it’s the opportunity to solve an unfairly hard problem in a way no one has before. The harder the problem the more exciting it is. As a chemical-turned-software engineer, I can say the thrill is the same. The Data Visualization Beginner’s Toolkit #1: Books and Other Resources One of the main goals of this blog, other than challenging the status quo with reflections at the intersection between academics and practitioners, is to help people become data visualization experts. It’s not rare for me to receive emails from people who are enthusuastic about visualization but have little guidance about how to become an expert. I have been posting some few articles in the past with this specific goal but I realized that they are too scattered and not organized in a way to represent an organic resource for the readers. For this reason, I decided to create a series specifically designed to help those of you guys who are excited about visualization but really don’t know how and where to start.

Teaching my 5 year old daughter to code… So I decided to try and teach my 5 year old daughter some basic logical thinking and development principals. My little girl's shown a keen interest in what I do for a job amongst other things recently. She's a great reader and writer for her age and so I started looking around for a simple scripting language or similar that I could teacher her. Now the thing to remember about kids is this, no matter how smart they are they all have the attention span of a gnat! 3 seconds max, if it's not interesting then they're not interested, period! This limited my scope significantly. Helpful Tips #10: Visualise your website content network with Gephi Sitemaps are so 2003 (nah, they’re OK really). But in today’s world of complex, interlinked sites, what if you would visualise the relationships and hubs within your (large) website, to bring them to life for stakeholders and colleagues?

We'll get it right next time: Gut vs Head Dan Gardner's Risk: The Science and Politics of Fear offers a psychological model for how we, as ex-hunter-gatherers, make decisions about stuff. Apparently we have two separate modes of thought, which psychologists call System One and System Two and Gardner, with rather more of an eye on bestseller status, calls Head and Gut. Instinctively, you can guess what those mean and some careful thought plus a bit of research would tell you you were right. Gut is where elections are won and lost.
