This fork of a line chart visualizes product sales trends from 2018 to 2024, with each product’s sales values plotted as a separate line and points. The chart uses D3 v7 APIs including `d3.csv`, `d3.scalePoint`, `d3.scaleLinear`, and `d3.line` to render an SVG with axes, grid lines, and a legend. Data is loaded from a remote CSV file.
