{"version":"1.0","type":"rich","title":"one work d3js","description":"This example shows a smiling face built from SVG primitives—a yellow circle with black stroke, two eyes, eyebrows, and an arc-based mouth—centered on a blue background. The eyebrows animate upward and back down using chained `transition().duration()` calls, creating a brief surprised expression. The code uses D3 v5 selections (`d3.select`) and the `d3.arc` shape generator to construct the mouth, with SVG attributes set for positioning and styling. No external data source is used; all elements are hardcoded.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/caf39d59d5d14c3b86f4b244f3c68e29?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
