{"version":"1.0","type":"rich","title":"Let's make a face with D3","description":"A smiley face rendered in SVG responds to mouse movement by shifting its eyebrows. The example demonstrates fundamental D3.js DOM manipulation using `d3.select` and `d3.append` to build the face from circles and paths, with the `transform` attribute controlling its position. Eyebrow movement is driven by event handlers that update the `cy` attribute of SVG elements. All drawing uses SVG primitives within a single `<svg>` element, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/281839ebd924487988a0b84969943d73?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
