This line chart visualizes yearly data from a CSV file, plotting values against years with a blue line on axes labeled "Year" and "Value." It uses D3 v7 to load the data via `d3.csv`, scales the x- and y-axes with `d3.scaleLinear`, and renders the line path using the `d3.line` generator. The chart explicitly appends axes, labels, and the line to an SVG element, with margins set to accommodate tick marks and text. The example demonstrates basic DOM manipulation and data binding in D3.
