Raphaël—JavaScript Library RGraph: HTML5 charts library (Open Source!) Unheap - A Tidy Repository Of jQuery Plugins jQuery Plugins and HTML5 UI Framework | Shield UI Cubism Mike Bostock Square, Inc. * for monitoring of production systems How do we use visualization? Anomaly detection - observe abnormal activity Capacity planning - extrapolate non-linear trends Crisis diagnosis - see interactions between services System design - don’t guess; decide empirically What are the benefits of visualization? Faster diagnosis - reduce impact Discovery of unexpected behavior - prevent downtime Increased situational awareness - make better decisions Or: The strengths & weaknesses of human perception. Why is visualization hard? Data is not information - transform data to make it meaningful Some visual channels are less effective - favor position Integrality is hard to avoid - three dimensions max. Aspect ratios matter. Stacking makes middle layers hard to read. Garish colors can be hard to see. Load and render data incrementally. Make better use of modern browsers. Combine position and color to reduce vertical space. A small library, not a system. Why a context? CPU (10s) Network (10s)
Crossfilter Fast Multidimensional Filtering for Coordinated Views Crossfilter is a JavaScript library for exploring large multivariate datasets in the browser. Crossfilter supports extremely fast (<30ms) interaction with coordinated views, even with datasets containing a million or more records; we built it to power analytics for Square Register, allowing merchants to slice and dice their payment history fluidly. Since most interactions only involve a single dimension, and then only small adjustments are made to the filter values, incremental filtering and reducing is significantly faster than starting from scratch. Crossfilter uses sorted indexes (and a few bit-twiddling hacks) to make this possible, dramatically increasing the performance of live histograms and top-K lists. Example: Airline on-time performance The coordinated visualizations below (built with D3) show nearly a quarter-million flights from early 2001: part of the ASA Data Expo dataset.

API Design One of the development tasks I do most often is designing the API for a reusable component. The components are usually for iOS (though sometimes they’re for OS X), and are invariably GUI controls or views of some kind. I’ve designed literally dozens of component APIs over the years, including for clients like Apple, and I’ve learned quite a bit about the process. This is an important topic, whether you’re an open source contributor, or working as part of a team on a large app, or just creating your own software. APIs are UX for developers. As we go through some guidelines, I’m going to use my most recently released open source GUI component, MGTileMenu, as an example where necessary. Desirable qualities API design is very much like user interface and user experience design. IntuitiveForgivingFrictionless As with any piece of software designed for use by humans, we have to think about the use cases. The developer interface What is the control? Class interface Rule 1: Use the local dialect
Tangle: a JavaScript library for reactive documents Tangle is a JavaScript library for creating reactive documents. Your readers can interactively explore possibilities, play with parameters, and see the document update immediately. Tangle is super-simple and easy to learn. This is a simple reactive document. When you eat 3 drag cookies, you consume 150 calories. This is the HTML for that example. When you eat <span data-var="cookies" class="TKAdjustableNumber"> cookies</span>, you consume <span data-var="calories"> calories</span>. And this is the JavaScript. Write your document with HTML and CSS, as you normally would. Try out some examples.
