{"version":"1.0","type":"rich","title":"Untitled","description":"A line chart displays annual total automotive sales in the United States, with the year on the x-axis and sales on the y-axis, titled \"各種能源日用量比較.\" The visualization uses D3.js and C3.js, loading data from a CSV file via `d3.csv` and rendering the chart as an SVG. The axes are labeled \"Year\" and \"Sales,\" with the sales line drawn in red. The D3 `scaleTime`, `scaleLinear`, and `line` generator construct the plot, while gridlines and tick marks are styled via CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b2e3e5ad7350414f89c2392ad9e371bd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
