This example demonstrates how a D3.js visualization can dynamically respond to browser resizing. A green X is drawn across an SVG element, with the stroke width and opacity set to create a bold, semi-transparent visual. The chart container fills the page via CSS, and the code uses the `clientWidth` and `clientHeight` properties of the DOM element to determine the current size. A `resize` event listener triggers the `redraw` function, which updates the SVG’s width and height attributes and repositions the two lines using a data join. The visualization relies on D3 v5 and standard SVG rendering.
