{"version":"1.0","type":"rich","title":"basic sleep data","description":"This interactive scatter plot visualizes sleep duration and bedtime across moon phases, with each bar representing one night of Fitbit sleep-tracking data. The x-axis marks moon phase values from 1 to 29, while the y-axis displays time of day, showing end-of-sleep hour and duration in hours. The React app uses `scaleBand` and `scaleLinear` from d3.v5 to position rectangular marks in an SVG. Data is fetched asynchronously from a JSON gist, with moon phases calculated via a simple algorithm and timestamps parsed using `timeFormat`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/15bf8af43f1248d8893e8309a0422bc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
