Composite Indicators Visualization: Exploration of Multivariate Temporal Changes Using Radial Visualization

We present a work in progress on visualization of a popular Measurement and Benchmarking method, namely Composite Indicators (CIs). Composite indicators are increasingly recognized as an important tool in policy analysis and public communication and are often used to reflect performances of different units (e.g., countries, regions or organizations). Existing CI visualizations introduce a variety of solutions for the complex challenge of presenting multi-dimensional, time-oriented hierarchic data. Radial visualizations are popular among these solutions because of CI’s multi-dimensionality, although different coding is in use. In our work, we aim to shed light on radial presentations for multivariate temporal changes, hoping to produce relevant guidelines for CI visualizations. We introduce some radial design options with static and dynamic time coding, as we explore the design space. In future work, we plan to formally implement, and deploy selected designs.
