One of the challenges for the IoT industry is data analysis and interpretation. Big data generated by the IoT devices is impractical if it cannot be translated into a language that is easy to understand, process and present a visual language. For this reason, IoT data visualisation is becoming an integral part of the IoT. Data visualisation provides a way to display this avalanche of collected data in meaningful ways that clearly present insights are hidden within this mass amount of information. This can assist us in making fast, informed decisions with more certainty and accuracy than ever before. It is thus vital for business professionals, developers, designers, entrepreneurs and consumers alike to be aware of the role that Visualization will and can play shortly. It is crucial to know how it can affect the experience and effectiveness of IoT products and services.
