{"version":"1.0","type":"rich","title":"HTML Starter","description":"A smiling face composed of SVG shapes animates its eyebrows upward over two seconds. The example demonstrates a minimal HTML page setup with D3 v5 and React, rendering a yellow circle for the head, two eyes, and an arc-based mouth. The code uses `d3.select`, `d3.arc`, and `transition().duration()` to animate rectangle elements representing eyebrows, all within a fixed 960×500 SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ad138eff429a4d7bbeef2bac9585df41?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
