{"version":"1.0","type":"rich","title":"Area Chart","description":"This area chart visualizes the relationship between age and average calories burned, using a lightsteelblue filled area with a steelblue stroke. The visualization aggregates a lifestyle CSV dataset by computing the mean calories burned for each age value. Built with D3 v7, the code uses `d3.rollup` and `d3.mean` to group and summarize the data, then renders the result as an SVG path via the `d3.area()` generator. Linear scales for both axes, axis generators, and descriptive labels complete the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc13d55cca8748b692f86df2166e029c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
