{"version":"1.0","type":"rich","title":"Fork of VizHub User Count Over Time","description":"This chart shows the growth of unique logged-in VizHub users from its August 2018 launch through March 2022. A black line chart traces the cumulative user count over time, with annotated milestones like the VizHub 1.0 release, a Kickstarter for 2.0, and the Datavis 2020 launch. The code uses D3 v4’s `d3.line`, `d3.scaleTime`, and `d3.scaleLinear` to render SVG paths and circles, while `d3-svg-annotation` adds callout labels for key events. Data comes from a CSV file of date and user totals.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/441ab92d14a543799bc90aef28ddb20c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
