General Update Pattern, III By adding transitions, we can more easily follow the elements as they are entered, updated and exited. Separate transitions are defined for each of the three states. Note that no transition is applied to the merged enter + update selection; this is because it would supersede the transition already scheduled on entering and updating elements. It's possible to schedule concurrent elements by using transition.transition or by setting, but it's simpler here to only transition the x-position on update; for entering elements, the x-position is assigned statically.

Tables are related by foreign keys, which are fields which store the value of a record field from another table. futurescaper:futuregrapher package Futuregrapher Network Visualization Javascript Library This library combines a number of D3 and custom features into a dynamic graph visualization library.

D3.js crash course Download - 126.9 KB Introduction Data-Driven Documents ([^]) is a javascript library that offers an interesting approach to visualization for the web.

January 31, 2013 Example of using Callbacks for nested calls showing the incidental complexity that results and how eventually the asynchronous paths need to be synchronized together. ImagePlot visualization software: explore patterns in large image collections What is ImagePlot? ImagePlot is a free software tool that visualizes collections of images and video of any size. It is implemented as a macro which works with the open source image processing program ImageJ. ImagePlot was developed by the Software Studies Initiative with support from the National Endowment for Humanities (NEH), the California Institute for Telecommunications and Information Technology (Calit2), and the Center for Research in Computing and the Arts (CRCA). See your whole image collection in a single visualization. Existing visualization tools show data as points, lines, and bars.

Using D3, backbone and tornado to visualize histograms of a csv file After being procrastinating for weeks the learning of D3.js and backbone.js I have finally made my first example using both libraries to explore (via histograms) a pandas DataFrame. The reason of the procrastination is very simple: I love python to much, because is probably the only language who is great in all areas (that I am interested at least): Great web frameworks as Django and Tornado - "fighting" with ruby (rails)Great Data Analysis packages such as pandas - "fighting" with RGreat machine-learning libraries such as scikit-learnProbably not the most successful but has a good gaming library pyGameIs a great general purpose language - I use it to program a robot for a NASA competition using a PS3 controller, serial-ports, web-server, cameras, and all in one languageAnd the list could go for hours

D3.js: How to handle dynamic JSON Data When I started with d3.js, I really struggled understanding how I could link data from a JSON feed to a SVG graph. I read a lot of tutorials but still, I couldn't find what I was looking for. Now that I know how d3.js behaves, I thought it would a good idea to share the things that I learned. How to convert d3.js SVG to PDF « Work Updates by Sergiy Nesterko on January 30th, 2012 Consider the following plot: The image above is an SVG created using d3.js. I am going to use it in a paper, so need to convert it to PDF. It so happened that how to do this is not common knowledge, as is mentioned in this blog (which is, by the way, a good and balanced source of information relevant to our profession). » Beyond Tag Clouds: TagArcs for Wordpress Tag Visualization (part I) Beyond Tag Clouds: TagArcs for WordPress Tag Visualization Tag clouds are very use­ful to vi­sua­lize the most fre­quently used tags on a web­site, e.g. a blog. This is done by stee­ring at­ten­tion through em­pha­si­zed words whose font size, co­lor or po­si­tion stands out. But not­hing can be found out about tem­po­ral re­la­tion of a tag's posts. For me this be­came evi­dently on my own tag cloud (see left) which still ra­tes 'Lima' at the lea­ding po­si­tion whe­reas the re­la­ted ar­ti­cles are more then three years old.

Quick scatterplot tutorial for d3.js When I code One of the many interesting things Github does are punchcards for repositories that can tell you when people work on their code. Unfortunately, they’re only per-repository and I was interested in per-user Github punchcards. So I made my own. Collecting the data was fairly straightforward, finding a simple tutorial/example of a scatterplot in d3.js proved to be less than trivial. A fascination with xml maps Fig 1 - MapD Twitter Map 80M tweets Oct 19 - Oct 30 Visualizing large data sets with maps is an ongoing concern these days. Just ask the NSA, or note this federal vehicle tracking initiative reported at the LA Times. Or, this SPD mesh network for tracking any MAC address wandering by. “There was of course no way of knowing whether you were being watched at any given moment.
