Numerical Existence: Reflections on Curating Artistic Data Visualization Exhibitions

Data visualization is often associated with efficiency and the production of insights. However, nonconventional visual works with data, particularly artistic visualizations, are less frequently discussed, despite some notable exceptions. Artistic visualization is typically presented and debated at conferences on data visualization and related areas in computing and design, usually involving an exhibition of works in parallel. While there are established exhibitions in electronic art, collective exhibitions focused on artistic data visualization, especially those independent of academic events, remain rare. Additionally, there is a notable gap in the literature regarding the curation of artistic data visualization exhibitions, whether in physical or online environments. This article addresses this gap by exploring the curatorial processes behind two artistic data visualization exhibitions, "Numerical Existence" and "Numerical Existence: Emergencies," held in Rio de Janeiro in 2018 and 2024, respectively. We will present an overview of artistic data visualization exhibitions, discuss the role and unique challenges of curation in this field, and share detailed insights from our curatorial experience with the two exhibitions. Furthermore, we will propose future directions for research and practice in the curation of artistic data visualization. Through this exploration, we aim to contribute to the practice of curating artistic data visualization, providing reflections and recommendations to enhance the development and appreciation of this emerging field.
