Local Tool Visualizes Claude Code Session Data
A developer has created a tool that visualizes Claude Code usage data stored locally on your machine. The tool reads session data from ~/.claude/ and generates an interactive visualization in a single HTML file.
What the tool does
The visualization uses a scrollytelling approach with D3.js charts similar to R2D3-style presentations. It displays:
- Daily activity timeline
- Project breakdown
- Tool usage statistics
- Coding rhythm heatmap
If you've run /insights commands in Claude Code, the tool also visualizes your goals, outcomes, and friction points from those sessions.
Technical details
The implementation is minimal:
- Zero dependencies
- Just a Python script and a single HTML file
- No npm or build step required
- All processing happens locally on your machine
The tool was built entirely using Claude Code, according to the developer. The source is available on GitHub at github.com/aybidi/claude-code-visualizer.
