  "Description": "Provides an S3 class to represent graph adjacency lists\nusing 'vctrs'. Allows for creation, subsetting, combining, and\npretty printing of these lists. Adjacency lists can be easily\nconverted to zero-indexed lists, which allows for easy passing\nof objects to low-level languages for processing.",
