Bar Chart
This example shows a static bar chart of nine numeric values, with the bars displayed in an SVG container. The chart uses a fixed dataset defined in the code and renders the bars using SVG rectangles, which are appended to the SVG element created via `d3.select` and `append`. The visualization relies on D3.js version 7 for SVG generation, though the code does not include any axes, labels, or interactive behaviors—only the raw bars are drawn. The bars are positioned and sized based on the provided data values, but the implementation does not show scaling or styling details.
