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 capacity to collect and store the data is increasing at a quicker rate compared to the ability to analyze it. Throughout the last decades, many automatic data analysis methods have been developed. However, the complex nature of countless problems makes it indispensable to feature human intelligence within an initial phase in 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 understanding of complex problems. Using advanced visual interfaces, humans may directly connect to the data analysis capabilities of today’s computer, permitting them to make well-informed decisions in complex situations.

Visual Analytics can be viewed just as one integral approach combining visualization, human factors, and data analysis. The figure illustrates the investigation areas linked to Visual Analytics. Besides visualization files analysis, especially human factors, including the parts of cognition and perception, play a crucial role from the communication between the human as well as the computer, plus in the decision-making process. When it comes to visualization, Visual Analytics concerns the areas of knowledge Visualization and Computer Graphics, with respect to data analysis, it pro?ts from methodologies coded 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 in order to gain knowledge from data. The figure shows an abstract introduction to the different stages (represented through ovals) and their transitions (arrows) within the Visual Analytics Process.
In lots of application scenarios, heterogeneous data sources have to be integrated before visual or automatic analysis methods can be applied. Therefore, the ?rst step can often be to preprocess and transform the data to derive different representations for even more 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.
Following the transformation, the analyst may select from applying visual or automatic analysis methods. If the automated analysis can be used ?rst, data mining methods are placed on generate styles of the original data. When a model is created the analyst has got to evaluate and refine the models, which could best be achieved by a lot more important the information. Visualizations allow the analysts to have interaction with the automatic methods by modifying parameters or selecting other analysis algorithms. Model visualization can then be familiar with evaluate the findings from the generated models. Alternating between visual and automatic methods is characteristic for that Visual Analytics process and creates a continuous refinement and verification of preliminary results. Misleading brings about an intermediate step can thus be found within an early on, ultimately causing better results as well as a higher confidence. If your visual data exploration is completed first, the person must what is generated hypotheses by an automatic analysis. User interaction using the visualization can be reveal insightful information, as an illustration by zooming in on several data areas or by considering different visual opinion of your data. Findings in the visualizations enable you to steer model building inside the automatic analysis. To sum up, inside the Visual Analytics Process knowledge may be gained from visualization, automatic analysis, and also the preceding interactions between visualizations, models, and also the human analysts.
