A horizontal bar chart displays student enrollment across ten computer science courses, with purple bars sorted from highest to lowest by the number of enrolled students. The visualization uses D3.js v7’s `scaleLinear` and `scaleBand` to map enrollment counts and course names, while `axisLeft` and `axisBottom` generate the categorical and numerical axes. Data is loaded from a CSV file via `d3.csv`, and the SVG rendering includes rotated axis labels for courses and enrollment counts.
