This bar chart displays student scores from a local CSV file, with each student's name on the y-axis and their score as the bar length on a linear scale from 0 to 100. The visualization uses D3 v5’s `scaleBand` for the categorical y-axis, `scaleLinear` for the numeric x-axis, and `axisBottom` and `axisLeft` to render the axes. The purple bars are drawn as SVG `<rect>` elements appended to the chart, and hovering over a bar triggers a CSS opacity change.
