The art of Pi (`pi`), Phi (`phi`) and `e` // Martin Krzywinski / Genome Sciences Center ▲ 2013 day ▲ 2014 day ▲ 2015 day ▲ 2014 approx day ▲ Circular art This section contains various art work based on , and that I created over the years. Parallel coordinates Parallel coordinates is a common way of visualizing high-dimensional geometry and analyzing multivariate data. This visualization is closely related to time series visualization, except that it is applied to data where the axes do not correspond to points in time, and therefore do not have a natural order. Therefore, different axis arrangements may be of interest. History[edit] Parallel coordinates were often said to be invented by Philbert Maurice d'Ocagne (fr) in 1885,[1] but even though the words "Coordonnées parallèles" appear in the book title this work has nothing to do with the visualization techniques of the same name (the book only describes a method of coordinate transformation, see fulltext PDF of the book by clicking the link in the references).

Speedometer Chart / Gas Gauge Chart A speedometer graph is comprised of multiple components to give the illusion of one chart. The background is an image or donut chart. The needle is created with a pie chart. The numbers and text are done with text boxes. 40 must-see vídeos about data visualization and infographics Our selection of keynotes, TED Talks and interviews by some of the top names in the field (The Joy of Stats, by Hans Rolling, one of the must-see videos) After the success of our collection of data visualization presentations a few weeks ago, we decided to push even further our research of multimedia resources and take the risk of selecting some videos. And we say risk, because the abundance of data visualization videos on the Internet is simply mind-blowing.
Clustergram: visualization and diagnostics for cluster analysis (R code) About Clustergrams In 2002, Matthias Schonlau published in “The Stata Journal” an article named “The Clustergram: A graph for visualizing hierarchical and . As explained in the abstract: In hierarchical cluster analysis dendrogram graphs are used to visualize how clusters are formed. I propose an alternative graph named “clustergram” to examine how cluster members are assigned to clusters as the number of clusters increases.
How to assess change readiness Summary and key action points The purpose of a change readiness assessment is to analyse the level of preparedness of the conditions, attitudes and resources, at all levels in a systemIn this context the word 'system' is being used to cover organisations, sectors, networks, national structures, or any other combination of elements that might together be the focus of a capacity development initiative., needed for change to happen successfully. The greater the complexity of the proposed change, the greater the importance of understanding whether and where there is readiness for change as this can be critical first for deciding whether it is appropriate to intervene and, if it is appropriate, about both the entry points and the types of intervention. Key action steps Definition of the scope of the proposed change: all key stakeholders need to know the full range of system components that need to be assessed. Introduction
37 Data-ish Blogs You might not know it, but there are actually a ton of data and visualization blogs out there. I'm a bit of a feed addict subscribing to just about anything with a chart or a mention of statistics on it (and naturally have to do some feed-cleaning every now and then). In a follow up to my short list last year, here are the data-ish blogs, some old and some new, that continue to post interesting stuff. Data and Statistics By the Numbers - Column from The New York Times visual Op-ed columnist, Charles Blow, who also used to be NYT's graphics director.Data Mining - Matthew Hurst, scientist at Microsoft's MSN, also the co-creator of BlogPulse.Statistical Modeling - We might disagree on certain things, but Andrew's blog is one of the few active pure statistics blogs.The Numbers Guy - Data-minded reporting from Carl Bialik of the Wall Street Journal.Basketball Geek - Like statistical analysis and basketball? Statistical/Analytical Visualization

The Organizational Change Readiness Assessment by Douglas B. Reeves In Chapter 2 we considered your personal change experiences. Diagram Software - The Best Choice for Diagramming All-in-one diagram software that makes it perfect for the following diagram software types. What's the diagram solution? Buy one diagram software that suits one group but forces the other to compromise and make do? Or purchase some separate diagram software for each department's special needs and hope that your company approves the purchase? What about none of the above?
Microbial evolution EBI researchers have changed our view of 4 billion years of microbial evolution. Christos Ouzounis and colleagues have gained intriguing quantitative insights into how gene families are transferred, not only 'vertically' through passage from one organism to its progeny, but also 'horizontally' through the exchange of genetic material between distantly related organisms. Since the time of Darwin, the evolutionary relationships between organisms have been represented as a tree, with the common ancestors at the base of the trunk and the most recently evolved species at the tips of the branches. Microbiologists have argued for a long time that this representation doesn't really hold true for microbes, which often exchange genes among different species. Their claim has been that the evolution of these organisms is better represented by a net.
Handbook of Management Scales The Handbook of Management Scales is a collection of previously used multi-item scales to measure constructs in empirical management research literature. Critical Introduction[edit] The Handbook of Management Scales was first edited by A. Wieland in 2010 and has since grown. It contains a collection of measurement scales, which are the basis for empirical research. Data visualization books: How to start your personal library The Excel Charts Blog There are many approaches to data visualization. Take well-know authors like Tufte, Cleveland, Ware, Few, Bertin or McCandless. There is some overlap, but they all approach data visualization from a different angle.
