{"version":"1.0","type":"rich","title":"vizhub.js!","description":"A D3.js visualization builds a smiley face in SVG, demonstrating fundamental DOM manipulation. The code uses `select('svg')` to access the canvas and `append` to create a green circle for the face, two eyes, eyebrows as rectangles, and a mouth drawn with an `arc()` path generator. Interactive eyebrow movement is shown in the accompanying YouTube video, though the static code only renders the initial face. The example illustrates core D3 selection and element-creation techniques within a 960x500 viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e17cf468d68e41fd9af15537cfdff298?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
