This example uses D3.js to render a pseudo line chart from six hardcoded data points. The code defines a line generator using `d3.line` and draws it as an SVG path element, styling the stroke with a thick black width, round line caps, and round line joins. The result is an approximation of a traditional line chart, where the thick, rounded strokes create a visual effect closer to a bar or dot plot rather than a precise line. It demonstrates the core mechanics of SVG path rendering and the `line` API from the D3 shape module.
