{"version":"1.0","type":"rich","title":"Area Chart Activity 8","description":"This example visualizes the cost of sales from 2000 to 2013 using an area chart with a smooth curve. Data is loaded from a CSV file and parsed to extract year and cost values. The visualization uses D3 v5 APIs including `scaleTime`, `scaleLinear`, `axisBottom`, `axisLeft`, `line`, and `area` to render the chart in SVG. The area under the line is filled with light green, while the line itself is black, with red tick labels and orange axis labels for emphasis.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/107f1880d7874795b97433bc2383ee5f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
