  Discovering and making sense of relevant literature is fundamental in any
scientific field. Node-link diagram-based visualization tools can aid this
process; however, existing tools have been evaluated only on small scales. This
paper evaluates Argo Scholar, an open-source visualization tool designed for
interactive exploration of literature and easy sharing of exploration results.
A large-scale user study of 122 participants from diverse backgrounds and
experiences showed that Argo Scholar is effective at helping users find related
work and understand paper connections, and incremental graph-based exploration
is effective across diverse disciplines. Based on the user study and user
feedback, we provide design considerations and feature suggestions for future
work.
