[AI-Generated Summary]: This visualization project from the 2025 Peking University Visualization Summer School explores the political significance of auspicious signs and calamitous omens during Empress Wu Zetian’s reign (684-705 CE). The team collected over 200 records from historical texts including the New and Old Tang History books, analyzing their temporal and spatial distribution patterns in relation to major political events. The interactive visualization features four functional zones: spatiotemporal distribution, event correspondence, attribute classification, and filtering interactions. The analysis reveals that nearly two-thirds of major political events coincided with clusters of auspicious signs and disasters, with notable concentrations in Luoyang and Chang’an. The project demonstrates how data visualization methods can provide new perspectives on understanding the role of celestial phenomena in political legitimacy and power construction in ancient Chinese political culture.
