{"version":"1.0","type":"rich","title":"VizHub User Count Over Time","description":"This line chart shows the growth in cumulative VizHub user accounts from August 2018 to March 2020. The x-axis displays time in days and the y-axis shows the user count, with annotation labels marking events like a medium post, a Kickstarter campaign, and a course launch. Built with D3 v4, it renders as an SVG using `d3.axisBottom`, `d3.axisLeft`, `d3.line` with a monotone curve, and `d3.annotationLabel` to highlight specific growth triggers. The data comes from a CSV file containing dates and user counts.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/612fab912bd44145b5bdfeba1d372350?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
