This combined line and area chart visualizes textile industry sales over time, using a yellow background with blue and red styling. The visualization loads CSV data from a GitHub gist and uses D3.js v5, with `d3.scaleTime` and `d3.scaleLinear` for axes, `d3.line` and `d3.area` with `curveBasis` for the smoothed curve and filled region, and `d3.axisBottom`/`d3.axisLeft` for tick marks. The SVG rendering includes bold axis labels and a red line over a wheat-colored area beneath it.
