{"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 basic SVG shapes. The code selects the SVG element and appends a circle with a radius of 200 pixels, while the accompanying stylesheet hides body margins and overflow. Using D3 v5’s `select` and `append` methods, the visualization shows how to programmatically create and style SVG elements, with related video content explaining animated eyebrow movement.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
