Cytoscape.js This is how easy it is to get started with Cytoscape.js (this code creates the instance you see on the bottom-right: About Cytoscape.js is an open-source graph theory library written in JavaScript. Cytoscape.js allows you to easily display and manipulate rich, interactive graphs. Cytoscape.js also has graph analysis in mind: The library contains a slew of useful functions in graph theory. Cytoscape.js is an open-source project, and anyone is free to contribute. The library was developed at the Donnelly Centre at the University of Toronto. Cytoscape.js & Cytoscape Though Cytoscape.js shares its name with Cytoscape, Cytoscape.js is not Cytoscape. Cytoscape.js is a JavaScript library: It gives you a reusable graph widget that you can integrate with the rest of your webapp with your own JavaScript code.

The Top 10 Javascript MVC Frameworks Reviewed - CodeBrief UPDATE 1/14/2012: Added Batman.js and Angular.js due to popular demand and because they looked impressive. Over the last several months I have been in a constant search for the perfect javascript MVC framework. Driven by a dire need for the right level of abstraction and features, I have tried out - some more cursorily than others - every framework I could get my hands on. Here lies a brief synopsis of each framework. Lastly, I share the framework which I ultimately decided on. Specifically, the following four features are very important to me: UI Bindings - I'm not just talking about templates, I'm talking about a declarative approach to automatically updating the view layer when the underlying model changes. The Contenders Here is a table showing all of the frameworks support for the above features. 1. Backbone.js is the web's darling framework. Pros: Strong community and lots of momentum. Cons: Lacks strong abstractions and leaves something to be desired. 2. Pros: Bindings support. 3.
If you’re disappointed with big data, you’re not paying attention There has been a backlash lately against big data. From O’Reilly Media to the New Yorker, from Nassim Taleb to Kate Crawford, everyone is treating big data like a piñata. Gartner has dropped it into the “trough of disillusionment.” It might be provocative to call into question one of the hottest tech movements in generations, but it’s not really fair. Correlation versus causation versus “what’s good enough for the job” One of the biggest complaints — or, in some cases, proposed facts — about big data is that is relies more on correlation than causation in order to find its vaunted insights. Honestly, for song or product recommendations, who really cares? But in areas like medicine, finance and even marketing, people are becoming much more concerned with finding out “why” once they’ve found out “what.” Or if you’re a retail store, knowing that Mac users who visit your site tend to buy more-expensive products might make you want to show them more-expensive products.
Flare | Data Visualization for the Web Superheroic JavaScript MVW Framework 6 Great Interactive Data Visualization Tools (Part 2) Welcome back for the second part of my series on interactive data visualization (dataviz) tools. In part one, we covered three cool tools for visualizing charts and graphs and many other data types on a webpage. In part two, we take a look at three more tools that are a bit more complex but have some incredible data visualization capabilities. 4. Exhibit is a very robust and customizable offering. Visualization Types Supported: Line Graphs, Maps, Scatter Plots, Multi-Filterable Lists, Timelines, Timeplots and more…with widgets! Flexible & Powerful Approach to Design I really like the approach of Exhibit, where data is presented through a "lens" – an HTML template shell that elements are placed into. Steep Learning Curve Like the other more complex libraries, there is more coding involved with Exhibit than most options, and having previous Javascript experience is definitely very helpful. 5. Javascript InfoVis Toolkit is a nice suite of tools for creating charts and graphs on a webpage.
Graphviz | Graphviz - Graph Visualization Software Introduction to RequireJS In this tutorial we are going to take a look at RequireJS, an AMD compatible asynchronous script loader that is incredibly powerful. In my experiments with RequireJS I've hugely enjoyed working with it and will be using it heavily in my future development. This is a fairly heavy post as far as complexity goes, but please do stick with it. I struggled to get my head around RequireJS and AMD for a long time but once it "clicks" it is really awesome. The basic use case for RequireJS is as a basic script loader, but in this tutorial I wont concentrate on that, but on its uses for modular development. RequireJS implements the AMD (Asynchronous Module Definition) spec, which means we can write our own modules and load them with RequireJS, allowing it to manage dependencies for us. To do this, we are going to build an app (sort of - it's all very basic snippets of code) that has dependencies. Firstly, create your project directory and the structure within. That line means whenever I do:
Business Intelligence and user adoption: A Depp-esc disaster? We’ve said it for a long time. In fact, we wrote a blog about it almost two years ago – What’s the Key Metric for Measuring BI Performance? The answer? “Simple – The rate of end-user adoption. That is, how many people in an organization who have access to BI software, actually use that software, and access the reports it generates, on a regular basis, to help them make operational and strategic business decisions.” And, much like the enduring partnership between Tim Burton and Johnny Depp – although their latest collaborative effort (Dark Shadows) received a dismal 42 percent rating on Rotten Tomatoes and had the LA Times wondering “has America fallen out of love with Johnny Depp?” Like our apparent overexposure to Burton and Depp’s quirky explorations of society’s social fringes, the necessity of BI user adoption is a message seemingly disregarded by an unreceptive audience – vendors and implementers alike. Research and advisory firms try again… Now back to that Aberdeen report… i. i. i.
