"Plotting solution sets for particular equations may be complicated by the existence of turning points. Here we describe an algorithm which not only overcomes such problematic points, but does so in the most general of settings. Applications of the algorithm are highlighted through two examples: the first provides verification, while the second demonstrates a non-trivial application. The latter is followed by a thorough run-time analysis. While both examples deal with bivariate equations, it is discussed how the algorithm may be generalized for space curves in $R^{3}$."

"Through most of the century, brackets were much closer to a continuous scale. There was a big shift in thought though in the 1980s, when Ronald Reagan was elected president. The brackets became much more distinct. The idea has more or less stuck over the past two decades."

"Raphaël is a small JavaScript library that should simplify your work with vector graphics on the web. If you want to create your own specific chart or image crop and rotate widget, for example, you can achieve it simply and easily with this library.
Raphaël uses the SVG W3C Recommendation and VML as a base for creating graphics. This means every graphical object you create is also a DOM object, so you can attach JavaScript event handlers or modify them later. Raphaël’s goal is to provide an adapter that will make drawing vector art compatible cross-browser and easy.
Raphaël currently supports Firefox 3.0+, Safari 3.0+, Opera 9.5+ and Internet Explorer 6.0+.
For more examples take a look at charting plugin: gRaphaël"

"The goal is not to make your user interface as realistic as possible. The goal is to add those details which help users identify what an element is, and how to interact with it, and to add no more than those details. UI elements are abstractions which convey concepts and ideas; they should retain only those details that are relevant to their purpose. UI elements are almost never representations of real things. Adding too much realism can cause confusion."

"See SVG Overview for lots of good reasons that you should use SVG."

"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. It uses JavaScript and SVG for web-native visualizations; no plugin required (though you will need a modern web browser)! Although programming experience is helpful, Protovis is mostly declarative and designed to be learned by example."

"ggplot2 is a plotting system for R, based on the grammar of graphics, which tries to take the good parts of base and lattice graphics and none of the bad parts. It takes care of many of the fiddly details that make plotting a hassle (like drawing legends) as well as providing a powerful model of graphics that makes it easy to produce complex multi-layered graphics."

"Mesh is a library for creating Voronoi, Delaunay and Convex Hull diagrams in Processing. After searching online for a Java package for creating Voronoi diagrams and failing to find anything simple enough to fit my needs I decided to make my own as simple as possible. I did find the wonderfully useful QuickHull3D package, which the algorithms for creating these diagrams are based on. These complete in O(n log n) time."

"PUT THAT PENCIL DOWN
Using Balsamiq Mockups feels like you are drawing, but it's digital, so you can tweak and rearrange controls easily, and the end result is much cleaner. Teams can come up with a design and iterate over it in real-time in the course of a meeting."

"You have the picture of a graph but not the corresponding data? You want to retrieve the trajectory of an object from a QuickTime movie? GraphClick is then simply the best way to solve the problem! You just have to click on the image and the obtained coordinates of the points can be directly exported into any other application."

There have got to be a thousand ways to use genetic programming in this space. "StudioGPU's MachStudio Pro reinvents the 3D visualization production pipeline by putting the power of real-time graphics processing at your fingertips.

"In this presentation, we review some fundamentals of visualization and then proceed to describe methods and combinations of methods useful for visualizing high dimensional data. Some methods include parallel coordinates, smooth interpolations of parallel coordinates, grand tours including wrapping tours, fractal tours, pseudo-grand tours, and pixel tours."

"This project aims to create an archive of user contributed clip art that can be freely used. All graphics submitted to the project should be placed into the Public Domain according to the statement by the Creative Commons. If you'd like to help out, please join the mailing list, and review the archives. "

"To sum up, I use R with Rails successfully and very happily, but under controlled circumstances and not in a public-facing or uptime-crucial situation. I don’t have data on speed or memory usage, other than to say that I regularly run reports with dozens or even hundreds of different images and graphics rendering is not the most time consuming part of the task. What matters most to me is that I can easily prototype in R, and my library of graph types can be used in any environment that supports R. I am not locking myself in to a Rails-only or Ruby-only package. Also, although I haven’t even touched on it here, my Rails and Ruby applications have access to the rest of R’s extensive statistical and mathematical functionality and a huge package library."

"When Allen Noren pointed to this visualization of U.S. government bailouts, I wanted to tweak it by showing the magnitudes on a timeline. I found this data set on Many Eyes, updated it with the number $700B, and made this bubble chart:..."

Watch the video, and admire the computer mimicking an artist painting a version of a computer-generated 3-d model. Beautiful.

I like the sepiatone effect of monochrome with tint but no inversion....
