Simple Visualizations with D3plus. I’ve been using D3, a JavaScript library for data visualizations (the three ‘D’s stand for Data-Driven Documents), for my own projects and with my students for some time.

Simple Visualizations with D3plus

It’s a particularly cool tool for working with dynamic data or information from a database and giving it life in a visual format through charts, graphs, and interactive data displays. Information visualization can be a powerful way to represent complex or otherwise inaccessible data. However, the learning curve for it is a little high, so I’ve never recommended it as an entry tool for this type of visualization. Last week I followed Miriam Posner’s mention on Twitter to something that may change that: D3plus. IBM Watson Analytics. How to Give a Killer Presentation. IBM Watson Analytics.

Think Again: Big Data. “Europe Is History.”

Think Again: Big Data

No. These days, many speak of Europe as if it has already faded into irrelevance. In the words of American pundit Fareed Zakaria, “it may well turn out that the most consequential trend of the next decade will be the economic decline of Europe.” According to Singaporean scholar Kishore Mahbubani, Europe “does not get how irrelevant it is becoming to the rest of the world.” Not a day went by on the 2012 U.S. campaign trail, it seemed, without Republican challenger Mitt Romney warning that President Barack Obama was — gasp — turning the United States into a “European social welfare state.” With its anemic growth, ongoing eurocrisis, and the complexity of its decision-making, Europe is admittedly a fat target right now. Power, of course, depends not just on these resources but on the ability to convert them to produce outcomes. Yes, the EU now faces an existential crisis. In one sense, it is true that Europe is in inexorable decline. Only part of it.

Hardly. No. Table of Contents — July-December 2014. Big Data: Pitfalls, Methods and Concepts for an Emergent Field by Zeynep Tufekci. Big Data, large-scale aggregate databases of imprints of online and social media activity, has captured scientific and policy attention.

Big Data: Pitfalls, Methods and Concepts for an Emergent Field by Zeynep Tufekci

However, this emergent field is challenged by inadequate attention to methodological and conceptual issues. I review key methodological and conceptual challenges including: 1) Inadequate attention to the implicit and explicit structural biases of the platform(s) most frequently used to generate datasets (the model organism problem). 2) The common practice of selecting on the dependent variable without corresponding attention to the complications of this path. 3) Lack of clarity with regard to sampling, universe and representativeness (the denominator problem). 4) Most big data analyses come from a single platform (hence missing the ecology of information flows).

20+ Tools to Create Your Own Infographics. A picture is worth a thousand words – based on this, infographics would carry hundreds of thousands of words, yet if you let a reader choose between a full-length 1000-word article and an infographic that needs a few scroll-downs, they’d probably prefer absorbing information straight from the infographic. What’s not to like? Colored charts and illustrations deliver connections better than tables and figures and as users spend time looking back and forth the full infographic, they stay on the site longer. Plus, readers who like what they see are more likely to share visual guides more than articles. While not everyone can make infographics from scratch, there are tools available on the Web that will help you create your very own infographics. In this article, we’re listing more than 20 such options to help you get your messages across to your readers, visually. SAP Lumira. The Social Life of Big Data and Algorithms.

The Social Life of Big Data and Algorithms

Searchlights and sunglasses: Field notes from the digital age of journalism. Big Data is a Big Deal. Posted by Tom Kalil on March 29, 2012 at 09:23 AM EDT [Editor's Note: Watch the live webcast today at 2pm ET of the Big Data Research and Development event at Today, the Obama Administration is announcing the “Big Data Research and Development Initiative.”

Big Data is a Big Deal

By improving our ability to extract knowledge and insights from large and complex collections of digital data, the initiative promises to help accelerate the pace of discovery in science and engineering, strengthen our national security, and transform teaching and learning. To launch the initiative, six Federal departments and agencies will announce more than $200 million in new commitments that, together, promise to greatly improve the tools and techniques needed to access, organize, and glean discoveries from huge volumes of digital data. Learn more about ongoing Federal government programs that address the challenges of, and tap the opportunities afforded by, the big data revolution in our Big Data Fact Sheet.
