A bar chart displays student scores from a CSV file, ranking each student on a vertical band scale against a linear grade axis. The visualization customizes axes by removing default domain lines, adding grid lines, and applying a formatting function that converts large numbers to abbreviated labels using D3's `format`. It uses `d3.csv`, `scaleLinear`, `scaleBand`, `axisLeft`, and `axisBottom` to render SVG bars with styled ticks and titles.
