This bar chart visualizes student test scores from a CSV file, with each student’s name on the x-axis and their numeric score on the y-axis ranging from 0 to 100. The visualization uses D3.js v7’s `d3.scaleBand` and `d3.scaleLinear` to map data to SVG rectangles filled with steel blue, while `d3.axisBottom` and `d3.axisLeft` render the axes. The code loads the data asynchronously via `d3.csv` and renders the chart entirely in SVG within a styled container.
