{"version":"1.0","type":"rich","title":"Fork of Interactive Sparkline","description":"This interactive sparkline visualizes weekly D3.js download counts, with a line and area chart that updates on mouse movement. The code uses d3.line, d3.area, d3.scaleTime, and d3.scaleLinear to render the chart, while d3.pointer and d3.bisector handle hover detection. Data is fetched from a remote JSON file and aggregated using d3.flatRollup and d3.sum. A hovered circle and vertical line highlight the selected week, with a text label showing the download count and date range.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f11b433fa4144fb8b2107bc4145d982f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
