Techniques in Data Visualization for Electrical Engineering: From Embedded Systems to the Internet

The emerging Internet-of-Things (IoT) concept is considered to be the next technological revolution [1]. It describes various technologies and research disciplines that enable the Internet to reach out into the real world of physical everyday objects. By 2020, it is expected that 25-50 billion “things” to be connected to the Internet. Gartner, the world's leading information technology research and advisory company, projects IoT will result in $1.9 trillion in global economic growth [2]-[3]. While today there are just 300,000 developers contributing to the IoT, a new report projects that an estimated 4.5 million developers are needed by 2020 [4]. This reflects a massive employment opportunity for future hardware and software engineers in IoT.
