Visualization Integration and Operation Linkage for Big Data from Large IoT System

Abstract

In a large scale IoT system, structured and unstructured data are collected from various distributed sensors. It is important to visualize these data with an overview context composed of multiple views and interactively focus on some detail views to understand the current system status. But a unified VA (Visual Analysis) is difficult owing to due to being short of expressly relationship between distributed datasets from different sensors or processed subsets of big data. In this paper, we present a visualization framework to analytically acquire the relationship among distributed or processed subsets, integrate their views in a visualization context, and realize operation linkage between them.
