{"version":"1.0","type":"rich","title":"VizHub User Count Projection","description":"A line chart tracks VizHub's registered users from its August 2018 launch to November 2020, projecting growth with an annotated curve. Two labels highlight a spike after a Medium post and a notable uptick during the VizHub 2.0 Kickstarter. Built with D3 v4, the SVG visualization uses `d3.line` with `curveMonotoneY`, time and linear scales, and gridlines via `d3.axisBottom` and `d3.axisLeft`. Annotations are added using the `d3-svg-annotation` library, and the chart resizes dynamically with the window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ceb90d4bb6294ec78bfdc51d04ad4c21?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
