{"version":"1.0","type":"rich","title":"Project Momentum Sleep Efficiency Dataset","description":"This visualization compares average sleep metrics by gender using a bar chart of data from a sleep efficiency CSV dataset. A dropdown menu lets users switch between features like sleep efficiency, exercise frequency, caffeine consumption, and sleep-stage percentages. The chart is built with D3 v7, using `scaleBand` for the categorical x-axis and `scaleLinear` for the y-axis, with custom axis labels. Data is fetched as CSV, parsed with `csvParse`, and aggregated on the fly for male and female averages.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fb742e0b75ac4742aa20370af77221c9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
