  Discovering and making sense of relevant research literature is fundamental
to becoming knowledgeable in any scientific discipline. Visualization can aid
this process; however, existing tools' adoption and impact have often been
constrained, such as by their reliance on small curated paper datasets that
quickly become outdated or a lack of support for personalized exploration. We
introduce Argo Scholar, an open-source, web-based visualization tool for
interactive exploration of literature and easy sharing of exploration results.
Argo Scholar queries and visualizes Semantic Scholar's live data of almost 200
million papers, enabling users to generate personalized literature exploration
results in real-time through flexible, incremental exploration, a common and
effective method for researchers to discover relevant work. Our tool allows
users to easily share their literature exploration results as a URL or
web-embedded IFrame application. Argo Scholar is open-sourced and available at
https://poloclub.github.io/argo-scholar/.
