This area chart by prashanthyamala visualizes product sales quantities from 2011 to 2020. Built with D3.js v5, it renders an SVG with a smooth basis curve for both the line and the filled area beneath it, which is colored orange. The chart uses scaleTime and scaleLinear for its axes, with axisLeft and axisBottom for ticks and labels. Data is loaded from a remote CSV file and parsed using d3.timeParse.
