{"version":"1.0","type":"rich","title":"Area Chart Activity 8","description":"This area chart displays the cost of sales from 2000 to 2013, using a green filled region beneath a black curve. The visualization loads CSV data via `d3.csv`, parses years as dates, and renders with SVG paths generated by `d3.area` and `d3.line` with a `curveBasis` interpolation. Axes are created using `d3.axisBottom` and `d3.axisLeft`, with scales from `d3.scaleTime` and `d3.scaleLinear`, while tick formatting uses `d3.format`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/82193ab3267448b8a785ba145d700499?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
