This example renders a static bar graph using D3.js, displaying categorical data as vertical bars. The visualization maps each data point to a rectangular bar, with bar height proportional to the value. It uses D3's scale functions to compute the x and y positions, along with SVG elements for rendering. The chart includes axes for reference and labels for readability. The data is hardcoded within the script rather than loaded from an external file, and the bars are styled with a uniform fill color.
