{"version":"1.0","type":"rich","title":"Vehicles Area chart ","description":"This area chart shows the average vehicle price by year, with a green shaded region rising and falling across the time series. The visualization uses D3.js to load CSV data from a GitHub gist, aggregate prices per year with `d3.rollup`, and render the area using `d3.area()` with a monotone curve. Axes, gridlines, and labels are created via D3’s axis APIs, while the SVG output is styled with CSS for a clean presentation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/436009ee9a804cf6ba80bf521beb282c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
