This example renders a full-screen red SVG with no visible content or data. The React component `LineChart` receives an empty `data` array and outputs an empty `<svg>` element sized to the viewport. The code imports `range` from d3 but never uses it, and the page title references a coronavirus line chart that does not appear in the implementation. The visualization relies on React 16.9, ReactDOM, and d3 v5, but only the SVG container is created.
