This example demonstrates the result of sorting a JavaScript array of numbers in ascending order using D3’s `d3.ascending` comparator. It shows the sorted array output in the browser’s console, not on the page. The code defines an array, calls `arr.sort()` with the D3 comparator, and logs the reordered values. The visualization is minimal, consisting only of a blank HTML page with a large placeholder message style, while the actual data processing relies on D3 v7 and JavaScript’s native array methods.
