{"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 smooth curve to show the trend over time. The visualization includes labeled axes and a shaded area beneath the line to highlight the magnitude of values. Built with D3 v5, it loads CSV data from a GitHub gist, parses the year and cost fields, and uses `scaleTime`, `scaleLinear`, `area`, `line`, and `curveBasis` to generate the chart. The SVG rendering is styled with CSS for tick colors, axis labels, and the light green fill.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f41a6cfbc53f4536a3591ae1f68d0502?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
