Statistical Visualization For his book The Visual Miscellaneum, David McCandless, along with Lee Byron, had a look at breakups on Facebook, according to status updates. They looked for the phrase "we broke up because" in status updates, and then graphed the frequencies over time. Why they couldn't just look at updates to relationship status, I'm not sure. Notice the peak leading up to the holiday season and spring cleaning. Finally, there's the highlight of Mondays, which you might lead you to believe that people like to call it quits during the beginning of the week. [Information is Beautiful | Thanks, Elise]
SimPy: Simulating Systems in Python by Klaus Müller and Tony Vignaux 02/27/2003 Simulating complex real-world systems is now possible with SimPy , an open source simulation package. SimPy, originally developed by the authors of this article, has been developed to production quality by a small team of enthusiastic open sourcerers around the world. As far as we know, it is the only existing discrete event Python simulation package. Actually, it is one of a very small number of fully object oriented simulation systems. Why consider simulation? To demonstrate using SimPy for simulation we will study a simple scenario. When customers call they may have to wait for a free line. To model "quality of service", we label a customer "happy" or "unhappy" depending on wait time. SimPy Setting up a simulation requires modeling the system under study, capturing the essential entities and their interactions, and then writing code to make the model executable. Simulated entities in SimPy are objects of the Process class. yield hold,self,t
Visual Mapping.com 18. Recursion — How to Think Like a Computer Scientist: Learning with Python 3 Recursion means “defining something in terms of itself” usually at some smaller scale, perhaps multiple times, to achieve your objective. For example, we might say “A human being is someone whose mother is a human being”, or “a directory is a structure that holds files and (smaller) directories”, or “a family tree starts with a couple who have children, each with their own family sub-trees”. Programming languages generally support recursion, which means that, in order to solve a problem, functions can call themselves to solve smaller subproblems. 18.1. Drawing Fractals For our purposes, a fractal is a drawing which also has self-similar structure, where it can be defined in terms of itself. Let us start by looking at the famous Koch fractal. An order 1 Koch fractal is obtained like this: instead of drawing just one line, draw instead four smaller segments, in the pattern shown here: Now what would happen if we repeated this Koch pattern again on each of the order 1 segments? 18.2. 18.3.
indiemapper is free - Axis Maps Blog by David Heyman on January 5, 2012 With the start of 2012, we’ve decided to make indiemapper free to use. Since indiemapper launched in 2010, our business has grown and changed to where supporting and maintaining indiemapper is no longer a major part of what we do at Axis Maps every day. We’re making indiemapper free so that it can continue to exist as a useful tool for map-makers while freeing us up to be as awesome as possible at our custom cartography business. To allow us to give it away for free, we’re scaling back what indiemapper does. We’re really happy about this change and we hope you are too. Launch indiemapper
Axis Maps LLC - Cartography. Visualization. Design. Infosthetics: the beauty of data visualization The beauty of information aesthetics: Visual Poetry 06 by Boris Müller. " Boris Müller's newest 'visual theme' for a annual international German literature festival. 2006 the theme consisted of beautiful visualizations of the poetry texts themselves. Each word corresponded to a numerical code by adding the alphabetical values of its letters together. This number was mapped onto the position on a circle, and marked by a red dot. Gray lines connect the dots in the sequence the words appear in the poem. Andrew Vande Moere digs deep in his information channels to gather the most interesting forms of data visualization. Written by Verena Stamen are amongst Andrew’s all time favorites. First, would you quickly sum up your background for us? Way back, I studied Architectural Engineering at the K.U.Leuven University in Belgium. I was lucky enough to become a post-graduate student there, then a research assistant, and finally a PhD student. Beautiful diagram, again from Stamen !
