This visualization maps the geographic distribution of institutional affiliations at American Comparative Literature Association (ACLA) conferences. The packed circle layout groups institutions by region, with circle size proportional to presentation count.
Institutions are classified into regions (US Northeast, Midwest, South, West, Canada, Japan, UK/Europe, East Asia, Oceania, Other) based on name matching against a 200+ entry dictionary.
HHI (Herfindahl-Hirschman Index): Measures concentration. Lower = more diverse. Top-5 %: Share of presentations from the 5 largest institutions. International %: Non-US share.
