# Knowledge graph Graph views are generated discovery aids and are not evidence. After reading the [home answer](https://uk-digital-healthcare-legal-requirements.pages.dev/index.md) or a [worked exchange](https://uk-digital-healthcare-legal-requirements.pages.dev/decision-workflow/index.md), use the [2D](https://uk-digital-healthcare-legal-requirements.pages.dev/graph/two-dimensional/index.md) or [3D](https://uk-digital-healthcare-legal-requirements.pages.dev/graph/three-dimensional/index.md) view, then verify every claim in canonical Markdown and the source register. The main subject is [what must be sent or made available digitally](https://uk-digital-healthcare-legal-requirements.pages.dev/digital-requirements/index.md). Individual care is primary, with planning, research and public health also covered. Source nodes retain their own scope; a graph connection does not establish a legal requirement.
