{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by constructing a smiley face from SVG shapes, with animated eyebrows that move upward and downward. The face is drawn entirely through D3 selections and attribute assignments, using `d3.select` to target the SVG element and chain methods like `.append` and `.attr` to build the circles and lines. The eyebrows animate via a recurring `setInterval` that toggles their vertical position, showcasing how D3 can update existing elements. Rendering is purely SVG-based, with styling handled by an external stylesheet that hides overflow for a clean presentation.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
