Automated Insights on Visualizations with Natural Language Generation
Quantitative data, such as a 10k financial report, requires cognitive load to scan the columns and rows and identify patterns and important takeaways, whether novice or subject matter expert. Visualizations can be used to summarize and reveal patterns. However, it may still be difficult to understand what is most meaningful. What should the viewer pay attention to? In this research, we reduce the cognitive load in understanding tabular data by combining charts with ranked natural language generated (NLG) bullet point statements that summarize the top takeaways.

Tile-Based Spatio-Temporal Visual Analytics via Topic Modeling on Social Media
We present a visual analytics system that supports the geospatiotemporal analysis of social media data based on a large-scale distributed topic modeling technique. Through the analysis of social media data in a given time and region, we can identify critical events in real time. However, it takes significant time to perform such analyses against a large amount of social media data. As a way to handle this issue, we developed an efficient tile-based topic modeling approach, which divides textual data into multiple subsets with respect to different regions and time frames at different zoom levels and applies topic modeling to each subset.

Anatomy of an Adaptive Scaffold for Analysts
Adaptive user interfaces offer the potential to improve the learnability of software tools and analytic methodologies by tailoring the operation and experience to a user’s needs. Scaffolding is an instructional strategy that can be applied by adaptive interfaces to achieve this. Scaffolding theory suggests that the level of guidance should be adjusted to optimize learning and performance levels. This paper explores the use of adaptive techniques to scaffold user interaction and presents a taxonomy of techniques for adaptive scaffolds within complex software systems. The techniques identified in the proposed taxonomy can help software scaffolds select appropriate adaptations in response to the user’s learning and operating needs. A scaffold called nAble was implemented to explore the application of adaptive techniques from the taxonomy to support an analysis methodology called the Analysis of Competing Hypotheses (ACH).

Visualization for Communication: The Importance of Aesthetic Sizzle
When creating a visualization for communication, the inclusion of aesthetically appealing elements can greatly increase a design’s appeal, intuitiveness and memorability. Used without care, this “sizzle” can reduce the effectiveness of the visualization by obscuring the intended message. Maintaining a focus on key design principles and an understanding of the target audience can result in an effective visualization for communication. This paper describes these principles and shows their use in creating effective designs.

GeoTime Information Visualization
Analyzing observations over time and geography is a common task but typically requires multiple, separate tools. The objective of our research has been to develop a method to visualize, and work with, the spatial inter-connectedness of information over time and geography within a single, highly interactive 3-D view. A novel visualization technique for displaying and tracking events, objects and activities within a combined temporal and geospatial display has been developed. This technique has been implemented as a demonstrable prototype called GeoTime in order to determine potential utility.

Visualization of Self-Reporting Entities for Command and Control
Several innovative visualization techniques have been developed during the DARPA Command Post of the Future (CPOF) program. One assumption of the program is that information will be gathered electronically from the individual platforms of friendly forces. New visualization techniques, combined with this hi-resolution platform-based or entity-level data, can be used to generate dramatically improved displays of the battlefield. This paper discusses the visualization methods that have been developed for effective presentation of this information to commanders.

Value in the Details: Understanding Data Through Visual Exploration
Analysts and data scientists work with large amounts of data, but the common approach, which dates back 20 years, is to roll up all the data into summary tables or charts, resulting in loss of detail. In contrast, direct visual exploratory analysis of massive amounts of raw data can yield insights that are otherwise overlooked. Here we highlight high-density visualizations that directly plot hundreds of millions of data points for applications such as market opportunity, periodicity analysis, and anomaly identification.

Visualizing Big Graphs and Social Networks
Big graphs are difficult to visualize because the scale of the data quickly results in complex network diagrams that can be difficult to decipher and have complicated interfaces with hundreds of options. Instead, we start by understanding what valuable nuggets we are trying to learn from this data, such as “Who’s connected to both me and my competition?” and “Did these people meet?” Starting from the question, we can then simplify the requirements and design effective visualizations that fit the problem. We will look at some mini-case studies and demos (e.g. Twitter correlation network, charity network) and some of the issues
