Data Visualization: Communication & Creativity

Data Visualization: Communication & Creativity | e-Xploration | Scoop.it

Visual communication skills are alien to some in the research industry, but they needn’t be. Data visualisation can become part of the research process through smart hiring, skills training and expert partnerships.


Data visualisation should not be regarded as an end in itself; the real point to data visualisation - the value that it brings to research buyers and suppliers - is as an aid to storytelling. It’s about seeing the patterns in the data that flush out a story and then help you to start telling that story. Only by doing that can you move data off the spreadsheet and out into the real world of consumer behaviour and preferences.

The best analogy and the one used frequently, is with journalism. It’s no surprise either that many great examples of data visualisation come from the publishing and media sectors. Journalists face the same challenge that we do of sifting large amounts of often conflicting data to arrive at a truth or an insight...

Karen Dietz's curator insight, February 6, 2013 4:48 PM

Here's the next stop on the data and visual storytelling journey. While the previous article I curated focused on the history of visual storytelling, this research article addresses 'what's next.'


For the authors of the article -- what's next is the presentation and communication of data that has played only a minor role in research up to this point.


Click on the title of the article "Storytelling: The Next Step for Visualization" at the bottom of the blurb to get a free copy of the research paper. 


The research paper itself focuses on journalism as storytelling -- which it is, but it is not the only method or approach. So the article is limiting in that way. 


Still, there are some good insights about how data visualization needs to move more directly into storytelling using story delivery techniques.


Iin the end, the authors Robert Kosara and Jock Mackinlay say: 

"Storytelling promises to open up entirely new avenues of research in visualization. Going from exploration to analysis to presentation is a natural progression, which is mirrored by the research effort focused on these steps over time. As the field becomes more mature and provides many useful techniques for the first two steps, we need to start focusing on presentation. This is even more important as visualization gets used for decision-making, where the succinct presentation of important facts is crucial."

Amira's curator insight, February 8, 2013 6:04 AM

"What if the very thing that made you feel crazy happy also made you smarter? That’s the question underlying the work of the Institute for Centrifugal Research, where scientists believe that spinning people around at a sufficiently high G-force will solve “even the trickiest challenges confronting mankind.” (...) The culminating experiment features a ride that resembles a giant tropical plant. Riders enter a round car that rises slowly up, up, up and then takes off suddenly at incredibly high speed along one of the “branches.”

“Unpredictability is a key part of our work,” says Laslowicz. After the ride, he says, people described experiencing a “readjustment of key goals and life aspirations.” Though he later adds that he wouldn’t put his own children on one of his rides. “These machines provide total freedom,” Laslowicz says, “cutting all connection to the world we live in: communication responsibility, weight. Everything is on hold when you’re being centrifuged.”

Common Crawl has so far indexed more than five billion pages, adding up to 81 terabytes of data, made available through Amazon’s cloud computing service. For about $25 a programmer could set up an account with Amazon and get to work crunching Common Crawl data, says Lisa Green, Common Crawl’s director.

 

Common Crawl also has Google’s director of research, Peter Norvig, and MIT Media Lab director Joi Ito on its advisory board.

Connecting a Connectome to Behavior: An Ensemble of Neuroanatomical Models of C. elegans Klinotaxis

Connecting a Connectome to Behavior: An Ensemble of Neuroanatomical Models of C. elegans Klinotaxis | e-Xploration | Scoop.it

Increased efforts in the assembly and analysis of connectome data are providing new insights into the principles underlying the connectivity of neural circuits. However, despite these considerable advances in connectomics, neuroanatomical data must be integrated with neurophysiological and behavioral data in order to obtain a complete picture of neural function. Due to its nearly complete wiring diagram and large behavioral repertoire, the nematode worm Caenorhaditis elegans is an ideal organism in which to explore in detail this link between neural connectivity and behavior. In this paper, we develop a neuroanatomically-grounded model of salt klinotaxis, a form of chemotaxis in which changes in orientation are directed towards the source through gradual continual adjustments. We identify a minimal klinotaxis circuit by systematically searching the C. elegans connectome for pathways linking chemosensory neurons to neck motor neurons, and prune the resulting network based on both experimental considerations and several simplifying assumptions. We then use an evolutionary algorithm to find possible values for the unknown electrophsyiological parameters in the network such that the behavioral performance of the entire model is optimized to match that of the animal. Multiple runs of the evolutionary algorithm produce an ensemble of such models. We analyze in some detail the mechanisms by which one of the best evolved circuits operates and characterize the similarities and differences between this mechanism and other solutions in the ensemble. Finally, we propose a series of experiments to determine which of these alternatives the worm may be using.

Is Data Visualization Art?

Is Data Visualization Art? | e-Xploration | Scoop.it

Data Visualization is driven by data. Its form is often derived from optimizing the efficiency of inputting data (and information about that data) into a human brain. It is a very pragmatic practice, built around numbers and logic.


And yet it is beautiful. It evokes emotions. It can be aesthetically pleasing, or hideous. It communicates complex concepts and provokes thought. It is consumed for enjoyment. Some visualizations even share similarities with poetry.

There are several stages in the life cycle of data visualizations, and while the core of the practice is driven by rational thinking, any number of stages in the process have opportunities for subjective decisions or artistic interpretations...

T N T — The Network Thinkers: Arrows on Twitter

T N T — The Network Thinkers: Arrows on Twitter | e-Xploration | Scoop.it
luiy's insight:
Arrows on TwitterTwitter is a social network that network scientists refer to as an asymmetric network -- the links are directional, they drawn with arrows.  Links between people on Twitter show direction of intent. The arrows are drawn from source to target.
         Looking at a social graph from Twitter we can tell a lot by following the arrows... who is aware of whom/what?whom/what is getting attention?who is involved in conversations on specific topics?who is central, and who is peripheral to the discussions?This past week I was invited to a Twitter Chat (a.k.a. Tweetchat) on the topic of Serendipity.  Two separate chat groups (#innochat and #ideachat) came together on a topic of overlapping interest.  Twitter chats last for 1 hour and use a pre-determined Twitter hash-tag to track all of the tweets in the on-line conversation.  When we draw a network map (a.k.a. social graph) we see people as nodes and their connections/conversations as links.  In this case, the links have arrows showing who is referring to whom.  Let's first look at outgoing links -- who is linking out, to whom.  Links on Twitter can be of a broadcast nature (X announces something to all of her followers).  Links can be directed at a specific target -- Y aims a message at a specific person, or Z re-tweets(RT) something X has posted.  Even though an RT is a broadcast, it is also a message back to the originator of the tweet -- I am aware of what you tweeted, and I choose to pass it on to others (not necessarily an endorsement).   The network map below shows participants from the Serendipity Tweetchat.  Two nodes are linked if the source node, RT'ed, MT'ed or @-messaged the target node: source —> target. Only those links where an interaction happened more than once, between the two nodes, are shown.  The node colors show: blue - general chat participant, purple - chat facilitators, green - invited guest.  The Twitter ID of each participant is shown beneath their node.  The node size is determined by a network metric calledAwareness -- it looks at all local, outgoing, direct and indirect, links surrounding a node.  The higher the awareness metric, the larger the node.  Larger nodes should be more aware of what is happening in the surrounding network, than the smaller nodes.

Software that tracks people on social media created by defence firm

Software that tracks people on social media created by defence firm | e-Xploration | Scoop.it

A multinational security firm has secretly developed software capable of tracking people's movements and predicting future behaviour by mining data from social networking websites.

A video obtained by the Guardian reveals how an "extreme-scale analytics" system created by Raytheon, the world's fifth largest defence contractor, can gather vast amounts of information about people from websites including Facebook, Twitter and Foursquare.

Raytheon says it has not sold the software – named Riot, or Rapid Information Overlay Technology – to any clients.
