{"version":"1.0","type":"rich","title":"Average REM Sleep Duration vs. Age","description":"This visualization shows how average REM sleep duration varies with age using data from a sleep efficiency dataset. The scatter plot displays age on the x-axis and average REM sleep percentage on the y-axis, with each point representing a distinct age group. The visualization uses D3.js v7 APIs including `scaleLinear`, `axisBottom`, `axisLeft`, and `flatRollup` to aggregate the raw CSV data into age-grouped averages. A dropdown menu lets viewers switch between different sleep metrics, though the default view focuses specifically on REM sleep patterns across the lifespan.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/bd7c26720e3a4175a9eaf545663e8e78?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
