{"version":"1.0","type":"rich","title":"Interpolation and Area Charts","description":"This interactive area chart visualizes three randomized data series, distinguishing state, national, and facility values by color. The visualization enables experimentation with different interpolation curves and easing functions. Users can dynamically change the interpolator, easing type, duration, or regenerate the data via buttons, which triggers animated transitions in the SVG rendering. The code leverages D3.js version 3.5.5, including its ordinal and linear scales, SVG axes, and interpolation methods like cardinal, monotone, and step, alongside custom easing functions such as elastic, bounce, and back.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-2e9a7bbfe2c237ccedd237b52125fec2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
