{"version":"1.0","type":"rich","title":"US Annual Auto Sales","description":"This chart shows US annual auto sales over time, with a line/area plot tracing the sales trend by year. The visualization uses D3 version 5’s `scaleTime` and `scaleLinear` for the axes, with a filled light-blue area beneath the line via the `area` generator. The code reads CSV data from a GitHub gist, parses the Year and Sales columns, and renders the chart as scalable vector graphics (SVG). Axis labels and a title are added using D3’s text elements, while the grid lines come from the `axisLeft` and `axisBottom` functions with negative tick sizes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3c5544b528754deeacb0a0e8636d1635?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
