{"version":"1.0","type":"rich","title":"Line Chart","description":"This line chart visualizes the average calories burned by age, using data from a lifestyle CSV file. The code aggregates individual records by age and calculates the mean calories burned, then plots the resulting trend as a smooth, steel-blue line. Built with D3 v7, it employs `d3.csv` and `d3.autoType` for data loading, `d3.rollup` for aggregation, and `d3.scaleLinear` for axes. The SVG rendering uses `d3.axisBottom` and `d3.axisLeft` for ticks, and a `d3.line` path for the trend, with custom labels for both axes and the title.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/676bc338b03640259cd3f5f3e8387003?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
