{"version":"1.0","type":"rich","title":"Activity 8_Task-4","description":"This area chart shows the cost of sales from 2000 to 2013, with a smooth curve and a light green filled region beneath the line. The visualization uses D3 v5’s `area()` and `line()` generators with `curveBasis` to create the path, while `scaleTime` and `scaleLinear` map the year and cost values. Axes are rendered via `axisBottom` and `axisLeft`, with tick formatting using `format('.3s')`. Data is loaded from a CSV file using `csv()`, and the SVG is positioned within a fixed 920x400 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27cc6266b3ef4d69a17c4d6efbaa9a8f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
