{"version":"1.0","type":"rich","title":"ICE--7","description":"This example visualizes the average vehicle fuel efficiency by year using a line chart with red data points and labeled values. The chart is built with D3 v7, loading CSV data from a cars dataset and parsing it with `d3.csvParseRows`. The code groups the data by year and calculates the mean mileage using `d3.rollup` and `d3.mean`, then renders the trend with a line generator and axes. The visualization is rendered as an SVG, showing how average MPG varies across model years.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/58190a996c5e4303b77c6201c0bc126f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
