ContactGraph

ContactGraph enables the extraction of contact lists and email metadata from Google services. It facilitates the creation of a centralized, private repository of professional relationships, allowing users to visualize their network density and communication history without relying on third-party social networking platforms.

This implementation is designed for data engineers, network analysts, and privacy-conscious professionals who require granular control over their personal relationship data. It serves individuals looking to perform custom relationship analytics or those needing to migrate contact information between private storage environments.

Users must possess valid Google Cloud Platform credentials to configure the required OAuth2 consent screen and scopes. Access to the Google People and Gmail services is mandatory, requiring the user to authorize the application to read contact and message metadata during the initial handshake process.
