{"version":"1.0","type":"rich","title":"ICE--7","description":"This area chart displays the average fuel mileage (MPG) of cars grouped by model year, using a dataset of 30 vehicles parsed from a CSV file. The visualization aggregates individual car records by year, then draws a steel-blue filled area with a darkblue boundary line, red circular data points, and numeric value labels. Built with D3 v7, the code uses `d3.csvParseRows` to clean the data, `d3.rollup` with `d3.mean` for aggregation, and `d3.area()` along with `d3.line()` generators to render the SVG paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/56415815702845099512465f7dba53f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
