This visualization shows electronic sales from 2013 to 2021 using a combined line and area chart. The line traces sales trends over time, while the filled area beneath emphasizes cumulative magnitude. The code uses d3.csv to load data from a GitHub gist, d3.scaleTime and d3.scaleLinear for axes, and d3.line with d3.curveBasis for the stroke. d3.area creates the shaded region, with axes rendered via d3.axisBottom and d3.axisLeft. SVG rendering and green/pink styling support the presentation.
