{"version":"1.0","type":"rich","title":"Hello D3 Version 6","description":"A demonstration of D3 version 6, this example draws a static smiley face as SVG circles and a path. Using `d3.select` and `append` to create elements, it animates the eyes with chained `transition().duration()` calls that alternately shrink and grow the circles' radii. The mouth is generated via `d3.arc()`, setting inner and outer radii with start and end angles, all rendered in an SVG canvas without external data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8f7879be4be04cac9fc20305b0889f42?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
