{"version":"1.0","type":"rich","title":"Activity8_Task4","description":"This area chart visualizes the cost of sales from 2000 to 2013, using a smooth curve to connect annual data points and a light green fill beneath the line to emphasize the trend. The visualization is built with D3 v5, employing `scaleTime` and `scaleLinear` for axes, along with `line` and `area` generators with `curveBasis` to create the smooth path. Data is loaded from a CSV via `d3.csv`, parsed into `Date` and numeric cost values, and rendered as an SVG with styled axis labels and tick marks.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8c8d8f4c05714569bd56181685ea4b33?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
