This line chart visualizes the relationship between petal width and petal length from the Flowers dataset. Using D3.js v7, the SVG visualization plots a monotone interpolated line with individual data points, showing the trend between the two measurements. The chart is constructed with D3 scales, a line generator, and axis components. The data is loaded from a remote CSV file, then rendered with a steelblue stroke for the line and orange circles for the data points on a white background.
