This example shows a blank SVG canvas and uses D3.js to demonstrate fundamental DOM manipulation, as described in the accompanying README. The code imports `select` and `arc` from the D3 v5 library, selects an SVG element with a fixed width and height, and begins to set up a visualization. While the title suggests a bar chart, the current implementation only initializes the SVG structure with no visible data or chart elements rendered. The visualization relies on D3’s selection and arc-generation APIs, with a simple HTML page linking to D3 v5.9.2 from a CDN and a separate stylesheet.
