{"version":"1.0","type":"rich","title":"animated line","description":"An animated line chart displays the changing popularity of a fictional topic over time, with an update button that regenerates the data to show the line redrawing itself with a smooth sinusoid easing. Built with D3.js (v7.8.5), the chart uses `scaleLinear` for axes, `line` for the path generator, and the `transition` API with `easeSin` to animate the stroke-dashoffset over 2.5 seconds. The SVG rendering includes axes and a steelblue path, with fake data defined in JavaScript rather than from an external source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a01792606c74aa1a30e562bff19dea1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
