This example renders an empty SVG canvas with a width of 900 pixels and a height of 500 pixels. The code selects the SVG element using D3’s `select` method and retrieves its dimensions. While the JavaScript imports `csv` from D3, no data is loaded or visualized, and the SVG remains blank. The example demonstrates a minimal setup using D3 v5 within a React framework, with no visible visual output or interaction.
