VALID: Visual Analytics and Stream Visualization

Visual Analytics and Stream Visualization (VALID) is a new web-based framework for the interactive visualization of streaming data. Based on the traditional server-client model, the platform is enhanced with effective analytical methods. It can process data streams for visual analytics and visualization, such as creating density maps and conducting similarity analyses. It makes sense of data reduction and real time interactive visualization, and is especially important for large datasets, such as those from geographic information systems, real-time air quality monitoring equipment, human traffic prediction systems, etc.
