    A Descriptive Framework for Stories of Algorithms
    (The Eurographics Association, 2019) Liem, Johannes; Henkin, Rafael; Wood, Jo; Turkay, Cagatay; Madeiras Pereira, João and Raidou, Renata Georgia
    Data-driven stories, widely used in journalism and scientific communication, match well with the recent focus on interpretable machine learning and AI explainability. Current technologies allow authors to break away from narratives that reflect traditional analytical workflows. To support designing such types of stories, we introduce a descriptive framework that helps identifying narrative patterns and other characteristics of algorithm-related stories. We describe the design space within the framework and demonstrate how to apply to an example of an algorithm-centered story, discussing potential future steps.

    Visualization of Tonal Harmony for Jazz Lead Sheets
    (The Eurographics Association, 2022) Bunks, Carey; Weyde, Tillman; Slingsby, Aidan; Wood, Jo; Agus, Marco; Aigner, Wolfgang; Hoellt, Thomas
    Jazz improvisation is the extemporaneous expression of melody, and musicians commonly base their performances on chord progressions given by lead sheets. It is standard practice to commit a progression to memory by analyzing it for common patterns. This paper presents a visualization design intended to help reduce the amount of cognitive work needed to assimilate a song's chords and harmonic patterns. It does this using color, shapes, and glyphs as visual variables to convey meaning about tonal centers, chord functions, and harmonic structure.
