A Tour through the Visualization Zoo

A Tour through the Visualization Zoo
Related Content Visualizing System Latency Heat maps are a unique and powerful way to visualize latency data. Explaining the results, however, is an ongoing challenge. Browse this Topic: Queue on Reddit Jeffrey Heer, Michael Bostock, and Vadim Ogievetsky, Stanford University Thanks to advances in sensing, networking, and data management, our society is producing digital information at an astonishing rate. 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. Creating a visualization requires a number of nuanced judgments. This article provides a brief tour through the "visualization zoo," showcasing techniques for visualizing and interacting with diverse data sets. Most of the visualizations shown here are accompanied by interactive examples. Time-Series Data Time-series data—sets of values changing over time—is one of the most common forms of recorded data.

Knowledge Visualization Scary Big Data, Cool 3D Analytics and More What’s going on in the analytics world this week? Big, Scary Big Data The New York Times did some “etymological detective work” to resolve the tricky question of who first coined the term “big data” in its current meaning (and some man-in-the street reporting shows that nobody really knows what they current meaning is). What we do know is that big data is powerful, and that means it’s also potentially scary. In the future, your credit rating might be determined by what you post on social networks. Not scared yet? The flip side of scary data is data that can save lives. 3D Meets Analytics 3D imaging meets dashboards with SAP Visual Enterprise: Gaming company Bigpoint use HANA to ensure Battlestar Galactica Online players stay in the game even after their ship has just been blown up: SAP HANA Is Music to Execs’ Ears (and Startups) SAP is helping disrupt business: here’s a nice balanced piece by ASUG about John Deere’s choice of SAP Business Suite powered by SAP HANA.

Free Open source Geocoder via REST webservices (for geonames and openstreetmap data) Documentation CanvasXpress works in all major browsers, Firefox, Safari, Chrome, Opera and IE. It even works in substandard browsers like Internet Explorer 6 if an additional javascript library like ExplorerCanvas or FlashCanvas is included. Older versions of many browsers like Firefox 1.5, Opera 9, Safari 3.x, Chrome 1.0, IE 6 also require additional javascript libraries, canvas-text and typeface.js to support printing of text. (Please see below). Javascript Libraries There are two or three JavaScript libraries that need to be included pedending on how to handle the fallback for older versions of IE. Flash fallback for older versions of IE VML fallback for older versions of IE How to initialize canvasXpress There are two ways to initialize CanvasXpress: var cX = new CanvasXpress(target, data, config, events); The function takes either one or four arguments which are explained in detail below. The parameter target is the id of the element in the DOM with the tag name <canvas>.

A second draft of a non-technical article on universality I’ve spent the last week or so reworking the first draft of my universality article for Mathematics Awareness Month, in view of the useful comments and feedback received on that draft here on this blog, as well as elsewhere. In fact, I ended up rewriting the article from scratch, and expanding it substantially, in order to focus on a more engaging and less technical narrative. I found that I had to use a substantially different mindset than the one I am used to having for technical expository writing; indeed, the exercise reminded me more of my high school English assignments than of my professional work. (This is perhaps a bad sign: English was not exactly my strongest subject as a student.) The piece now has title: “E pluribus unum: from complexity, universality”. By coincidence, I moved up and expanded the other US-centric item – the discussion of the 2008 US presidential elections – to the front of the paper to play the role of the hook. 1. Do I contradict myself? Fig 2. Fig 3. 2.

Graph Visualization and Neo4j So far we’ve learned how to get Neo4j up and running with Neography, how to find friends of friends and degrees of separation with the Neo4j REST API and a little bit of the Gremlin and Cypher languages. However, all we’ve seen is text output. We haven’t really “seen” a graph yet, but that’s about to change. Vouched holds a graph of skill specific recommendations people have made to each other and visualizes it. I extracted the visualization, and hosted it on github as neovigator. You can get your very own visualization up and running or take a look at this instance running on Heroku. Let’s get it up and running and then we’ll go through some pieces of the code. Then visit localhost:9292 to see it running. The website is a Sinatra Application with only two routes. The JSON object we create will have this structure: When we fill this JSON object and pass it to the visualization, this is what we get: We create a route in Sinatra and set it to return JSON.

Link Grammar Davy Temperley Daniel Sleator John Lafferty The Link Grammar Parser is a syntactic parser of English, based on link grammar, an original theory of English syntax. Given a sentence, the system assigns to it a syntactic structure, which consists of a set of labeled links connecting pairs of words. The parser also produces a "constituent" representation of a sentence (showing noun phrases, verb phrases, etc.). We have made the entire system available for download on the web. The system is written in generic C code, and runs on any platform with a C compiler. There is an application program interface (API) to make it easy to incorporate the parser into other applications.

The Digital Capabilities Your Company Needs These days, the most fundamental technology requirements are not just the responsibility of your IT department. New research suggests that digital transformation will require companies to draw from a core set of four digital capabilities: a unified digital platform; solution delivery; analytics capabilities; and business and IT integration. Image courtesy of Flickr user In today’s business environment, digital capabilities are a fundamental building block with which companies can transform customer experience, operational processes and business models. Our in-depth interviews with 157 executives in 50 large companies found that the most fundamental technology requirement for digital transformation is not particular skills or particular technologies. The most fundamental technology enabler (or inhibitor) of transformation is a digital platform of appropriately integrated data and processes.

Clickable chart of distribution relationships Probability distributions have a surprising number inter-connections. A dashed line in the chart below indicates an approximate (limit) relationship between two distribution families. A solid line indicates an exact relationship: special case, sum, or transformation. Click on a distribution for the parameterization of that distribution. Follow @ProbFact on Twitter to get one probability fact per day, such as the relationships on this diagram. More mathematical diagrams The chart above is adapted from the chart originally published by Lawrence Leemis in 1986 (Relationships Among Common Univariate Distributions, American Statistician 40:143-146.) Parameterizations The precise relationships between distributions depend on parameterization. Let C(n, k) denote the binomial coefficient(n, k) and B(a, b) = Γ(a) Γ(b) / Γ(a + b). Geometric: f(x) = p (1-p)x for non-negative integers x. Discrete uniform: f(x) = 1/n for x = 1, 2, ..., n. Poisson: f(x) = exp(-λ) λx/ x! Uniform: f(x) = 1 for 0 ≤ x ≤ 1. jdc

There are risks and rewards from outsourcing, and companies that do so need to carefully manage the process.
