{"version":"1.0","type":"rich","title":"Fork of VizHub User Count Over Time","description":"A line chart shows the cumulative number of VizHub users from August 2018 to July 2021, with circular markers at each data point. The chart uses D3 v4's `scaleTime`, `scaleLinear`, `axisBottom`, and `axisLeft` to build the axes and grid, while `d3.line` draws the path. Annotations via the `d3-svg-annotation` library highlight key events such as the VizHub 1.0 release, a Kickstarter campaign, and the launch of a Datavis 2020 course. The SVG renders the full chart and grid, with data loaded from `users.csv`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dc38f9a2fa7d44f7b7089a0b104ce07a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
