## Features

- Data visualization with charts (line + points, legend)
- Drawing canvas with color and width controls
- File management with open/save dialogs
- Tabbed UI (Chart / Drawing / File Manager)

## Requirements

cargo install --locked trunk
trunk serve
```

> Note: native file dialogs (rfd) only work on desktop builds.
