{"version":"1.0","type":"rich","title":"SVG Example","description":"This example draws a smiling face in SVG using D3 v5, with a yellow circular head, two eyes, rectangular eyebrows, and an arc-shaped mouth. The eyebrows animate by moving vertically over two seconds using chained `transition()` calls, shifting down then back up. The code uses `d3.select`, the `arc()` generator from D3’s shape module, and attribute setters like `.attr()` to construct the SVG elements. Static properties for spacing and sizing are defined as variables, and the entire face is centered within a 960×500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/23cd287584ed48739bac45ac1f7401e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
