{"version":"1.0","type":"rich","title":"Area Chart Activity 8","description":"This area chart visualizes the cost of sales from 2000 to 2013, with a smooth, curved line tracing the trend and a light green fill beneath it. Built with D3 v5 and rendered as an SVG, the visualization uses `scaleTime` and `scaleLinear` for the axes, with `axisLeft` and `axisBottom` providing tick marks and labels. The smooth line and area are generated via `line()` and `area()` with `curveBasis` for interpolation. It loads its data from an external CSV file, parsing the year values as dates and cost as numbers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/08ef72f6c19a40a7bdaeab4ff521ad4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
