{"version":"1.0","type":"rich","title":"v7 curve interpolation comparison","description":"This visualization compares eight d3.js v7 interpolation curves—including linear, step, basis, cardinal, monotoneX, and Catmull-Rom—by rendering the same time-series dataset (stock closing prices from April to May 2012) as overlapping SVG line paths. Each curve is drawn with a distinct color and labeled in a legend; clicking a label toggles the corresponding line’s opacity with a transition. The chart also includes scatterplot circles for the raw data points and uses d3.axisBottom and d3.axisLeft for the time and value scales.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-68175197ad39341c13f8099d035eae8a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
