This example displays a series of thin horizontal rectangles that collectively span the full width of the browser window, using a minimal design that emphasizes simplicity. The SVG canvas is dynamically sized to match the viewport dimensions. The visualization is built with D3.js, leveraging the `select`, `append`, `range`, and `join` APIs to generate and position each rectangle vertically, with a fixed height of 10 units. The data is synthetic, derived from a numeric range of 100 values, resulting in a clean, unadorned grid-like pattern rendered directly in the browser.
