{"version":"1.0","type":"rich","title":"VizHub User Count Over Time","description":"A line graph tracks the cumulative number of unique logged-in VizHub users from August 2018 to May 2022, with dots marking each recorded total and annotated callouts highlighting growth events like a Medium post and the VizHub 2.0 Kickstarter. The chart uses d3.scaleTime for the x-axis, d3.scaleLinear for the y-axis, and d3.line to draw the path, while d3-svg-annotation adds the notes. Data comes from a CSV file with dates and user counts, rendered as SVG in a responsive viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/229f32eba9614436aa97d485fb05ae6a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
