{"version":"1.0","type":"rich","title":"linechart","description":"This line chart tracks the growth in cumulative unique logged-in VizHub users over time, from the platform’s launch in August 2018 through early 2023. It shows the overall upward trend, with annotations highlighting notable events such as a Medium post, the VizHub 2.0 Kickstarter, and the Datavis 2020 course launch. The visualization uses D3 v4 with SVG rendering, employing `d3.scaleTime`, `d3.scaleLinear`, and `d3.line` for the chart, and `d3.axisBottom` and `d3.axisLeft` for axes. It also uses the d3-svg-annotation library to add explanatory labels directly on the chart.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/5bb5226253e544059aafcf8960a1ff17?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
