Build an Interactive Graph Editor Using TypeScript

In this project, we’ll develop a fully interactive system that helps users organize and visualize information as a connected graph.

We’ll start by defining the core data structure for nodes and edges, then build the graph canvas to render these elements visually. After that, we’ll implement features such as creating and editing nodes, defining relationships between concepts, and selecting nodes to view detailed information.

We’ll also add important productivity features such as undo/redo history management, importing and exporting graph data, and persistent storage so the user’s knowledge graph remains available across sessions.

By the end of the project, you will have built a working knowledge graph editor that can be used as a visual second brain, a planning tool, or a learning roadmap system:

• Personal knowledge management:

  • Connect concepts from courses, books, and tutorials.

  • Build mind maps for learning and studying.

  • Organize ideas as a visual “second brain.”

• Software and team planning:

  • Map system components and dependencies.

  • Link features to modules and APIs.

  • Plan epics, sprints, and architecture diagrams.

• Organizational knowledge:

  • Create onboarding maps (roles → tasks → tools).

  • Link internal documents and processes.

  • Map dependencies across departments.

• Learning and research:

  • Break down complex topics into prerequisites.

  • Create thesis structures (chapters → gaps → references).

  • Visualize dataset → model → metrics flow.
