This example shows a line chart of stock closing prices over time, with clear labels for both the x-axis (“Date”) and y-axis (“Value”). It uses d3.csv to load time-series data, d3.timeParse to convert date strings, and d3.scaleTime and d3.scaleLinear to map data to screen coordinates. The line is drawn as an SVG path with d3.line, and the axes are rendered via d3.axisBottom and d3.axisLeft. Custom text elements are appended to label the axes, demonstrating how to add axis titles in d3 v4.
