This example visualizes rice production in the US from 1991 to 2021 using a line chart rendered in SVG. The chart plots production volume in tonnes against parsed year values, with axes, gridlines, and labels styled via CSS. It loads CSV data from a GitHub gist and uses D3 v5 APIs including `csv`, `scaleTime`, `scaleLinear`, `line`, `axisBottom`, `axisLeft`, and `extent` to generate the visualization. The line path is drawn in purple with a stroke width of four pixels.
