Extracting useful patterns from large network datasets has become a fundamental
challenge in many domains. We present VISAGE, an interactive visual graph
querying approach that empowers users to construct expressive queries, without
writing complex code (e.g., finding money laundering rings of bankers and
business owners). Our contributions are as follows: (1) we introduce graph
autocomplete, an interactive approach that guides users to construct and refine
queries, preventing over-specification; (2) VISAGE guides the construction of
graph queries using a data-driven approach, enabling users to specify queries
with varying levels of specificity, from concrete and detailed (e.g., query by
example), to abstract (e.g., with "wildcard" nodes of any types), to purely
structural matching; (3) a twelve-participant, within-subject user study
demonstrates VISAGE's ease of use and the ability to construct graph queries
significantly faster than using a conventional query language; (4) VISAGE works
on real graphs with over 468K edges, achieving sub-second response times for
common queries.
