{"version":"1.0","type":"rich","title":"Fork of Fork of Fork of Area Chart","description":"This chart shows ten years of car sales as a single black line with a filled area beneath it, using smoothed curves via `d3.curveBasis`. The visualization loads a CSV from a GitHub gist, parsing the year and sales columns, then renders the axes and marks as SVG paths. It uses `d3.scaleTime` and `d3.scaleLinear` to map data, and `d3.axisBottom` and `d3.axisLeft` for grid lines and tick labels. The chart is generated entirely with D3 v5 and rendered as SVG within a centered HTML layout.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/40f32a1acd96476c90b0d4ef58cabcfd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
