{"version":"1.0","type":"rich","title":"Timeline","description":"This timeline visualization shows the growth of VizHub users from its launch in August 2018 through March 2021, with each user count plotted as a circle along a time axis. The code loads articles.csv containing New York Times COVID-19 and climate articles, using their publication dates to position cyan circles in the same timeline. Built with D3 v6, it uses `d3.scaleTime`, `d3.axisBottom`, and `.tickSize` to render the grid, while mouseover events display article URLs via appended text elements. The SVG canvas resizes responsively using `document.body.clientWidth` and `clientHeight`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/37fa89587f514d3dae2b301c6a49e73b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
