WHAT IS VISUAL ANALYTICS – BY DR JOERN KOHLHAMMER

Massive sets of data are collected and stored in many areas today.

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.

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.
