    STRAD Wheel: Web-Based Library for Visualizing Temporal Data
    (Institute of Electrical and Electronics Engineers, 2017) Diana Fernondez-Prieto; Carol Naranjo-Valero; José Tiberio Hernández; Hans Hagen
    Recent advances in web development, including the introduction of HTML5, have opened a door for visualization researchers and developers to quickly access larger audiences worldwide. Open source libraries for the creation of interactive visualizations are becoming more specialized but also modular, which makes them easy to incorporate in domain-specific applications. In this context, the authors developed STRAD (Spatio-Temporal-Radar) Wheel, a web-based library that focuses on the visualization and interactive query of temporal data in a compact view with multiple temporal granularities. This article includes two application examples in urban planning to help illustrate the proposed visualization's use in practice.
