The visualization uses d3.csv to fetch and parse the data, then displays the summary in an HTML pre element. The code also includes commented alternatives using the Fetch API with async/await and d3.csvParse, as well as an older nested-fetch pattern. The data merges CDC, NCHS, and SSA sources, with 2000–2003 values averaged between datasets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a2185013bb384e81a6ae67a40bf0195a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
