{"version":"1.0","type":"rich","title":"Answer2","description":"This interactive area chart displays the monthly count of Hubway bike-sharing trips over time, with data loaded from a remote TSV file. The visualization uses D3 v7’s `d3.rollups` to aggregate trip records by month and `d3.area` with a monotone curve to render the filled path. Hovering over any of the plotted circles triggers a tooltip showing the exact month and trip count. The SVG chart includes rotated time-axis labels and axis generators `d3.axisBottom` and `d3.axisLeft`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0cc009582b104d55abf241ca0921e7c1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
