This example demonstrates how an SVG visualization can respond dynamically to browser resizing by reading the container’s computed CSS dimensions and applying them to the drawing. It renders a simple green X composed of two diagonal lines using `d3.select` and `data` binding, with the `redraw` function called on the `window` `resize` event. The chart container uses fixed positioning, and the SVG size is updated via the `attr` method based on `clientWidth` and `clientHeight`, ensuring the graphic always fills the page.
