This stylized line chart displays an array of seven data points as a smooth, cardinal-interpolated curve, with axes labeled by index and value. The SVG rendering uses a D3.js v3 line generator to map the data, while the y-axis includes a rotated “Price($)” label. The chart’s gray background and steelblue stroke come from CSS rules, and the axes are drawn with `d3.svg.axis()`. The source data is a simple inline array.
