{"version":"1.0","type":"rich","title":"VizHub User Count Over Time","description":"This line chart shows VizHub user growth from its August 2018 launch through February 2020. The SVG visualization uses d3.line with a monotone curve, with each data point marked by a circle whose tooltip reveals the exact user count. Annotations from d3-svg-annotation highlight three growth events: a Medium post, the VizHub 2.0 Kickstarter, and the Datavis 2020 course launch. The code reads a local CSV file with user counts per date, and implements custom axes with tick marks and labels from d3.axisBottom and d3.axisLeft.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7cb657053510486c81e38d25a7750867?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
