This example demonstrates a React and D3.js integration that loads a single SVG path from a text file and renders it as a thin, colored line positioned in the upper right of the viewport. Using a `ResizeObserver` hook to track container dimensions, it builds an SVG element via `select` and `join` operations from D3 v7. The path responds to hover with a slightly thicker stroke width, while the overall container maintains a clean, minimalist design with the Inter font.
