The data size is growing rapidly than constantly, which means we have to be better prepared to be able to handle them, process and get some intelligence out ot it. One intuitive way to absorb the magnitude of it is to visualize in real-time.
According to Friedman (2008) the "main goal of data visualization is to communicate information clearly and effectively through graphical means. It doesn’t mean that data visualization needs to look boring to be functional or extremely sophisticated to look beautiful. To convey ideas effectively, both aesthetic form and functionality need to go hand in hand, providing insights into a rather sparse and complex data set by communicating its key-aspects in a more intuitive way.
