A minimal interactive visualization using React and D3 v6 displays a blank canvas that fills the browser window. The page sets the body to hide overflow and logs the computed height to the console, but no data or visual elements are rendered. The code imports the full D3 library but does not call any visualization functions, leaving the space empty. It demonstrates a bare-bones setup for future chart development, relying on `window.innerWidth` and `window.innerHeight` for sizing.
