This example shows crop production by year as an area chart with a superimposed line, using a yellow filled area and a thick black line. The x-axis uses a time scale for dates, while the y-axis uses a linear scale for production values, with grid lines and labeled axes. Built with React, the visualization leverages d3.csv for data loading, d3.line and d3.area with curveBasis for smooth paths, and d3.axisBottom and d3.axisLeft for ticks, rendering output as SVG.
