We investigate visitor interactions with, and responses to, EcoWebWater, a touch-based exhibit visualizing a 3D Antarctic food web. The aim is to gain knowledge about how public science center visitors engage with an interactive visualization about ecological relationships. The study employed a mixed-methods design using quantitative data from 995 visitor sessions logged at a science center, complemented by qualitative insights obtained through semi-structured interviews with five participants. The analysis focused on session durations, user behaviors, the nature of engagement, and responses to the exhibit. The quantitative analysis revealed patterns of engagement, categorizing session durations into short (<30 seconds), medium (30 seconds to 5 minutes), and long (>5 minutes) sessions. Longer sessions were characterised by exploratory behaviors, including increased page visits and food web interactions per session, while shorter sessions exhibited lower levels of engagement. The average session time was approximately two minutes, consistent with existing research on similar exhibits. Qualitatively, visitors demonstrated scientific reasoning, with interpretations ranging from correct to hybrid or incorrect. The exhibit also elicited a range of affective responses, e.g., curiosity and anxiety. However, user feedback indicated challenges with the 3D format, node density, and cognitive demands, which at times impeded usability and visual communication. This study provides new insights into public engagement with complex science visualizations, highlighting the importance of design considerations in enhancing accessibility and sustained interaction. The findings suggest potential design improvements to address identified challenges. Future research directions include exploring strategies to optimise user experience and increase engagement with interactive science center exhibits.
