Developed comprehensive documentation for the Graph Visualizer feature in the arangodb/docs-hugo repository, focusing on enabling developers to explore, edit, and customize ArangoDB graphs through the updated user interface. The work detailed processes such as viewing graphs, adding nodes and edges, inspecting properties, and utilizing layout and customization tools, while clearly outlining limitations like the lack of support for anonymous graphs and the requirement for write permissions to edit. Leveraging Markdown and technical writing skills, the documentation aligned with recent UI changes and arangodb/docs-hugo standards, improving onboarding for new users and reducing potential support queries through clear, structured guidance.
