What is Visual Analytics?
Visual Analytics
Visual Analytics is the science of analytical reasoning based on interactive visual interfaces. Today, data is produced at an incredible rate and also the capability to collect and keep the data is increasing faster compared to the capability to analyze it. During the last decades, numerous automatic data analysis methods have been developed. However, the complex nature of several problems makes it indispensable to add human intelligence within an initial phase from the data analysis process. Visual Analytics methods allow decision makers to combine their human ?exibility, creativity, and background knowledge with the enormous storage and processing capacities of today’s computers to achieve insight into complex problems. Using advanced visual interfaces, humans may directly connect to the data analysis capabilities of today’s computer, letting them make well-informed decisions in complex situations.

Visual Analytics is seen as an integral approach combining visualization, human factors, and knowledge analysis. The figure illustrates the study areas associated with Visual Analytics. Besides visualization information analysis, especially human factors, including the areas of cognition and perception, play a crucial role inside the communication between your human and also the computer, plus in the decision-making process. When it comes to visualization, Visual Analytics concerns areas of Information Visualization and Computer Graphics, and with respect to data analysis, it pro?ts from methodologies developed in the ?elds of knowledge retrieval, data management & knowledge representation as well as
data mining.
The Visual Analytics Process
The Visual Analytics Process combines automatic and visual analysis methods with a tight coupling through human interaction to be able to gain knowledge from data. The figure shows an abstract breakdown of the different stages (represented through ovals) and their transitions (arrows) within the Visual Analytics Process.
In many application scenarios, heterogeneous data sources have to be integrated before visual or automatic analysis methods can be applied. Therefore, the ?rst step is frequently to preprocess and transform the data to derive different representations for additional exploration (as shown by the Transformation arrow within the figure). Other typical preprocessing tasks include data cleaning, normalization, grouping, or integration of heterogeneous data sources.
After the transformation, the analyst may select from applying visual or automatic analysis methods. If the automated analysis is used ?rst, data mining methods are put on generate kinds of the initial data. When a model is created the analyst has to evaluate and refine the models, which may best be performed by a lot more important the info. Visualizations let the analysts to have interaction together with the automatic methods by modifying parameters or selecting other analysis algorithms. Model visualization may then be familiar with assess the findings from the generated models. Alternating between visual and automatic methods is characteristic for the Visual Analytics process and results in a continuous refinement and verification of preliminary results. Misleading leads to medium difficulty step can thus be found within an early on, bringing about better results and a higher confidence. If your visual data exploration is conducted first, the person has got to what is generated hypotheses by an automatic analysis. User interaction with the visualization is necessary to reveal insightful information, as an illustration by zooming in on several data areas or by considering different visual opinion of the data. Findings in the visualizations can be used to steer model building inside the automatic analysis. To sum up, inside the Visual Analytics Process knowledge may be gained from visualization, automatic analysis, plus the preceding interactions between visualizations, models, and also the human analysts.
