Navigate to this Imgur link. There are visualizations of a WiFi signal. Fascinating. I had no idea that the best signals were found on tops of wave “clouds.”
Excellent idea and work.

MakeUseOf offers us a list of graphic-making options in its “4 Data Visualization Tools for Captivating Data Journalism.” Writer Brad Jones describes four options, ranging from the quick and easy to more complex solutions. The first entry, Tableau Public, may be the best place for new users to start. The write-up tells us:
“Data visualization can be a very complex process, and as such the programs and tools used to achieve good results can be similarly complex. Tableau Public, at first glance, is not — it’s a very accommodating, intuitive piece of software to start using. Simply import your data as a text file, an Excel spreadsheet or an Access database, and you’re up and running.
“You can create a chart simply by dragging and dropping various dimensions and measures into your workspace. Figuring out exactly how to produce the sort of visualizations you’re looking for might take some experimentation, but there’s no great challenge in creating simple charts and graphs.
“That said, if you’re looking to go further, Tableau Public can cater to you. It’ll take some time on your part to really understand the breadth of what’s on offer, but it’s a matter of learning a skill rather than the program itself being difficult to use.”

Short honk: A visualization of some Wikipedia articles is available at this link.
The visualization includes a search box. It is helpful. I did not understand the dots of light that flew across the display. The display held my attention for a short period of time.

Watson has been going to town in different industries, putting to use its massive artificial brain. It has been working in the medical field interpreting electronic medical record data. According to Open Health News, IBM has used its technology in other medical ways: “IBM Research Scientists Investigate Use Of Cognitive Computing-Based Visual Analytics For Skin Cancer Image Analysis.”
IBM partnered with Memorial Sloan Kettering to use cognitive computing to analyze dermatological images to help doctors identify cancerous states. The goal is to help doctors detect cancer earlier. Skin cancer is the most common type of cancer in the United States, but diagnostics expertise varies. It takes experience to be able to detect cancer, but cognitive computing might take out some of the guess work.
Using cognitive visual capabilities being developed at IBM, computers can be trained to identify specific patterns in images by gaining experience and knowledge through analysis of large collections of educational research data, and performing finely detailed measurements that would otherwise be too large and laborious for a doctor to perform. Such examples of finely detailed measurements include the objective quantification of visual features, such as color distributions, texture patterns, shape, and edge information.”
IBM is already a leader in visual analytics and the new skin cancer project has a 97% sensitivity and 95% specificity rate in preliminary tests. It translates to cognitive computing being accurate.
Could the cognitive computing be applied to identifying other cancer types?

The brief article on Searchblox titled A Visualization Is Worth a Thousand Search Results relates the addition of visualization to the Elasticsearch-based system, Searchblox. Searchblox is an open source enterprise content search engine founded in 2003. Its customers range over 25 countries and include Harley Davidson, Capital One Investments, Kellog, and the US Department of Justice, to name just a few. The article discusses the latest advancement of visualization with a note on how to use the new plugin and how it works. The article states,
“Create a visualization from your search results using our new AngularJS database plugin and discover unique insights from your data. The AngularJS plugin integrated the raw/d3js javacsript library to create visualizations on the fly for your analysis, content marketing and infographic needs. After you setup your collections, simply install the plugin and configure the required filters and database columns to display.
Once the data grid is configured you can see the search results in a grid format.”
The article stipulates that the plugin is best suited for data from csv files and databases. The ability to see your results as a graphic rather than a list is certainly promising, especially for people who are visual learners. There are several nifty chart options available, for all of which the user is able to state the fields for their data.

The article on WMC Action News 5 titled Centrifuge Analytics v3 is Now Available- Large Scale Data Discovery Never Looked Better promotes the availability of Centrifuge Analytics v3, a product that enables users to see the results of their data analysis like never before. This intuitive, efficient tool helps users dig deeper into the meaning of their data. Centrifuge Systems has gained a reputation in data discovery software, particularly in the fields of cyber security, counter-terrorism, homeland defense, and financial crimes analysis among others. Chief Executive Officer Simita Bose is quoted in the article,
“Centrifuge exists to help customers with critical missions, from detecting cyber threats to uncovering healthcare fraud…Centrifuge Analytics v3 is an incredibly innovative product that represents a breakthrough for big data discovery.” “Big data is here to stay and is quickly becoming the raw material of business,” says Stan Dushko, Chief Product Officer at Centrifuge Systems. “Centrifuge Analytics v3 allows users to answer the root cause and effect questions to help them take the right actions.”
The article also lists several of the perks of Centrifuge Analytics v3, including that it is easy to deploy in multiple settings from a laptop to the cloud. It also offers powerful visuals in a fully integrated background that is easy for users to explore, and even add to if source data is complete. This may be an answer for companies who have all the big data they need, but don’t know what it means.

I find the metadata hoo hah fascinating. Indexing has been around a long time. If one wants to dig into the complexities of metadata, you may find the table from InfoLibCorp.com helpful:
Mid tier consulting firms often do not use the products or systems their “experts” recommend. Consultants in indexing do create elaborate diagrams that make my eyes glaze over.
Some organizations generate metadata without considering what is required. As a result, outputs from the systems can present mind boggling complex options to the user. A report displaying multiple layers of metadata can be difficult to understand.
My thought is that before giving the green light to promiscuous metadata generation, some analysis and planning may be useful. The time lost trying to figure out which metadata is relevant to a particular issue can be critical.
But consultants and vendors are indeed impressed with flashy graphics. Too many times no one has a clue what the graphics are trying to communicate. The worst offenders are companies that sell visual sizzle to senior managers. The goal is a gasp from the audience when the Hollywood style visualizations are presented. Pass the popcorn. Skip the understanding.

The information page titled What You Can Do With: Presto on Software AG Products provides an overview of the data-combining software formerly known as JackBe until its acquisition by Software AG. JackBe is now Presto! (Exclamation point optional.) Information flow since March 2014 has been modest. The article offers an overview and some of the capabilities of the software, such as in-memory analytics and visualization and data mashing. The article states,
“Presto combines data from any source for data visualizations. Accessing the original data—directly from data warehouses, news feeds, social media, existing BI systems, streaming big data, even Excel spreadsheets—lets business users respond to changing conditions as they happen. Presto’s “point-click-connect” assembly tool, Wires, makes it easy to bring together and manipulate data from multiple existing systems into meaningful data visualizations. Simple, powerful data mashing means IT and power users can create new apps and dashboards in hours—even minutes…”
Software AG began in 1969 in Germany and in 2013 acquired JackBe. According to the Company History page, the deal was actually awarded the title of Strategic M&A deal of the Year by the Association for Corporate Growth. Other acquisitions include Apama Complex Event Processing Platform, alfabet AG, and Longjump.

I read “72 Hours of #Gamergate.” I don’t follow the high buck world of video games. The write up contains oodles of data. Some of the information is in the form of bar charts. Other information is presented in words, spreadsheets, and graphics. I am okay with the bar charts. These have labels and numbers on the x and y axes. The visualization show below baffles me:
The image adds graphic impact. I have been in briefings in which senior executives and military brass have presented similar visualizations.
I suppose clarity is less important than sizzle. Analytics vendors, are you listening? I think not if this graphic is any indication of the way data are presented.

Data is no longer just facts, figures, and black and white graphs. Data visualizations are becoming an increasingly important way that data (and even Big Data) is demonstrated and communicated. A few data visualization solutions are making big waves, and Visage is one on the rise. It is highlighted in the FastCompany article, “A Tool For Building Beautiful Data Visualizations.”
The article begins:
“Visage, a newly launched platform, provides custom templates for graphics. There are myriad tools on the market that do this (for a gander at 30 of them, check out this list), but Visage is the latest, and it’s gaining traction with designers at Mashable, MSNBC, and A&E. That’s due in part to Visage’s offerings, which are designed to be more flexible, and more personalized, than other services.”
More and more companies are working on ways to help organizations decipher and make sense of Big Data. But what good is the information if it cannot be effectively communicated? This is where data visualizations come in – helping to communicate complex data through clean visuals.
