Visualization is a powerful tool for presenting complex data, but challenges of inspiration and ideation can hinder the creative process of designing compelling visualizations. We developed VisDice, a novel tool for stimulating creative thought and inspiring alternative design ideas to address this. By introducing randomness, VisDice prompts designers to explore uncharted territories and consider unconventional visualization solutions. This paper investigates VisDice's role in enhancing the creative process, drawing from psychological theories of inspiration. We explore how VisDice stimulates innovative thinking, leading to visually compelling designs. Our findings contribute to understanding the psychology behind creativity in visualization, offering practical insights for designers seeking to enhance their practices. Embracing the possibilities offered by VisDice unlocks new avenues for designing impactful visualizations.
