{"version":"1.0","type":"rich","title":"sugar","description":"This visualization displays daily blood glucose readings as multi-line time series, with each day’s measurements plotted against the time of day. A shaded horizontal band marks the target glucose range, while the most recent day’s line and points are highlighted in red. The code loads CSV data from a Google Spreadsheet via `d3.csv`, nests records by date using `d3.nest`, and renders SVG paths with `d3.svg.line` and cardinal interpolation. Circles mark individual glucose samples, and a dropdown menu populated by dates filters the highlighted series.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-ccfbff89e9f2da9e7089?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
