WHAT IS VISUAL ANALYTICS – BY DR JOERN KOHLHAMMER
Massive sets of data are collected and stored in many areas today. As the volumes of data available to business people or scientists increase, it becomes harder and harder to use the data effectively. Keeping up to date with the flood of data using standard tools for data management and analysis is far from easy. The field of visual analytics tries to provide people with better and more effective ways to understand and analyze these massive data sets, while helping them to follow up on their findings immediately, in real-time. Visual analytics integrates the analytic capabilities of the computer and the abilities of the human. This means, the human is empowered to take control of the analytical process; he or she is not just the final stage of a reporting process. Visual analytics sheds light on unexpected and hidden insights, which may lead to innovation and increase profits. For example, many key performance indicators are simply calculated using statistical models. But the true relations between data, models and business objectives often remain unclear. If visualization is included as an integral part of the analysis process then comprehension of the models as well as of the data is increased. Errors in the basic assumptions of the models can be recognized early on and newly discovered dependencies in the data can lead to new and possibly better reporting indices.
