This bar chart visualizes the number of Nobel Prizes awarded per category, using data parsed from a CSV file containing laureate information. The D3.js v7 code loads the data, counts prizes by category, and renders the results using `scaleBand` and `scaleLinear` for axes. Bars are colored steelblue and sorted in descending order by prize count. The SVG visualization includes rotated category labels on the x-axis, a title, and axis labels, with the underlying data rows also including year, prize share, and laureate details.
