This example demonstrates a simple D3.js data binding workflow that appends paragraphs to the page based on an array of numeric values. The code uses D3 v5’s `select`, `selectAll`, and `.data()` with `.enter()` and `.append()` to create text elements, with `.text()` showing each number. While the commented-out sections include CSV loading and bar chart rendering, the active code only displays the paragraph updates and logs “hello” to the console. The visual output is plain HTML paragraphs under a fixed SVG container, with no visible chart or data visualization rendered.
