{"version":"1.0","type":"rich","title":"Interactive Sparkline","description":"This interactive sparkline visualizes weekly NPM package download counts for the d3 library, using data fetched from a JSON URL. The chart displays an area and line graph, with a hover interaction that reveals a large numeric download count and a date range label. The implementation leverages d3 functions such as `scaleTime`, `scaleLinear`, `line`, `area`, `flatRollup`, `bisector`, and `pointer` to handle aggregation, scaling, and mouse tracking. The visualization updates dynamically as the mouse moves, highlighting the nearest data point with a circle and vertical line.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e75cae4d4dd04d7eb6f5041f31b5d869?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
