leads to new challenges in the analysis process, since analysts, decision makers, engineers, or emergency response teams depend on information "concealed" in the data.
field of visual analytics focuses on handling massive, heterogenous, and dynamic volumes of information through integration of human judgement by means of visual representations and interaction techniques
combination of related research areas including visualization, data mining, and statistics that turns visual analytics into a promising field of research.
The methods for data analysis must change because of the large amounts of data that have been collected over the years.
presents interactive visualization as an alternative and effective data exploration method for understanding the complex behaviors of computer network systems.
facilitates human-data interaction by highlighting patterns, anomalies and alert conditions in reporting views...tables of data ready for human consumption.
This is the basic definintion of visual data analysis
Some of these tools, such as Visokio Omniscope, are powerful hybrid desktop/web visualisation clients that can replace spreadsheets, presentation packages like PowerPoint, and create portable, reusable data files anyone can access, navigate and filter using a free viewer.
These are some ways that visual data analysis is changing our world.
enables data to be interpreted holistically by exposing contextually meanful attributes of the data set such as patterns, trends, structure, and exceptions.
