We present Graphie, a novel navigational interface to visualize Acts and Bills included in the UK’s legislation digital repository legislation.gov.uk. Graphie provides a network representation of the hierarchical structure of an Act of Parlia-
ment, which is typically organized in a tree-like fashion, according to the content and information contained in each sub-branch. Nodes in Graphie represent sections of an Act (or individual provisions), while links embody the hierarchical connections
between them. The legal map provided by Graphie is easily navigable by hovering on nodes, which are also color-coded and numbered to provide easily accessible information about the underlying content. The full textual content of each node is
also available on a dedicated hyperlinked canvas. The building block of Graphie is Sofia, an offline data pipeline designed to support different data visualizations by parsing and modelling data provided by legislation.gov.uk in open access form. While we focus on the Housing Act 2004 for illustrative purposes, our platform is scalable, versatile and provides users with a unified toolbox to visualise and ex-
plore the UK legal corpus in a fast and user-friendly way.
