Flot: Attractive JavaScript plotting for jQuery Datavisualization.ch Selected Tools Cube Time Series Data Collection & Analysis Cube is a system for collecting timestamped events and deriving metrics. By collecting events rather than metrics, Cube lets you compute aggregate statistics post hoc. It also enables richer analysis, such as quantiles and histograms of arbitrary event sets. Cube is built on MongoDB and available under the Apache License on GitHub. Collecting Data An event in Cube is simply a JSON object with a type, time, and arbitrary data. Cube’s collector receives events and saves them to MongoDB. Querying Events Cube defines a simple language for querying events. You can intersect filters and customize which event fields are returned. request(browser).gt(duration, 250).lt(duration, 500) Cube supports both HTTP GET and WebSockets for retrieving events. Querying Metrics You can also use Cube to group events by time, map to derived values, and reduce to aggregate metrics. The first few results of which appear as: sum(request.eq(path, "/search")) sum(request(duration))

Backbone.js Backbone.js gives structure to web applications by providing models with key-value binding and custom events, collections with a rich API of enumerable functions, views with declarative event handling, and connects it all to your existing API over a RESTful JSON interface. The project is hosted on GitHub, and the annotated source code is available, as well as an online test suite, an example application, a list of tutorials and a long list of real-world projects that use Backbone. Backbone is available for use under the MIT software license. You can report bugs and discuss features on the GitHub issues page, on Freenode IRC in the #documentcloud channel, post questions to the Google Group, add pages to the wiki or send tweets to @documentcloud. Backbone is an open-source component of DocumentCloud. Downloads & Dependencies (Right-click, and use "Save As") Backbone's only hard dependency is Underscore.js ( >= 1.5.0).

laverdet/node-fibers SVG Graphics Library for JavaScript HTML5 :jsDraw2DX Protovis Protovis composes custom views of data with simple marks such as bars and dots. Unlike low-level graphics libraries that quickly become tedious for visualization, Protovis defines marks through dynamic properties that encode data, allowing inheritance, scales and layouts to simplify construction. Protovis is free and open-source, provided under the BSD License. Protovis is no longer under active development.The final release of Protovis was v3.3.1 (4.7 MB). This project was led by Mike Bostock and Jeff Heer of the Stanford Visualization Group, with significant help from Vadim Ogievetsky. Updates June 28, 2011 - Protovis is no longer under active development. September 17, 2010 - Release 3.3 is available on GitHub. May 28, 2010 - ZOMG!

Manual Stability: 3 - Stable To use the HTTP server and client one must require('http'). The HTTP interfaces in Node are designed to support many features of the protocol which have been traditionally difficult to use. HTTP message headers are represented by an object like this: Keys are lowercased. In order to support the full spectrum of possible HTTP applications, Node's HTTP API is very low-level. http.STATUS_CODES# A collection of all the standard HTTP response status codes, and the short description of each. http.createServer([requestListener])# Returns a new web server object. The requestListener is a function which is automatically added to the 'request' event. http.createClient([port], [host])# This function is deprecated; please use http.request() instead. Class: http.Server# This is an EventEmitter with the following events: Event: 'request'# function (request, response) { } Emitted each time there is a request.
