An empty SVG canvas is prepared for a chart, but the visualization itself is not implemented in the provided code. The page loads D3 v5.9.2, sets up a 960-by-500-pixel SVG element, and links to external styles and JavaScript files. While the current code shows only the setup, the structure indicates the intended chart would be drawn as vector graphics using D3’s selection and attribute methods. The data source and rendering approach are not yet defined in this partial example.
