{"version":"1.0","type":"rich","title":"Fork of Interactive Sparkline","description":"This interactive sparkline charts weekly NPM download counts for the d3 package, as fetched from a remote JSON data source. The visualization displays a purple area chart with a bold line, and hovering over the chart reveals a vertical guide and a large text label showing the exact weekly total and date range. The implementation uses the d3 library, specifically `scaleTime`, `scaleLinear`, `line`, `area`, and `bisector`, along with `flatRollup` and `sum` to aggregate daily data into weekly buckets.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8462cfbb8dd5408b938ca2d12259d290?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
