GraphQL Voyager is a schema visualizer and data model explorer that provides an interactive graph representation of a GraphQL API. It serves as a documentation tool for inspecting types and fields by transforming schema introspection data into a visual interface.
The tool maps the relationships between different types and fields, allowing for the analysis of complex data models and their connections. Users can filter the visual representation to remove deprecated fields or wrapper classes and use a dedicated information panel to examine technical specifications for specific data types.
