{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"A yellow circle with a black outline forms a simple face in the center of an SVG canvas, demonstrating basic D3.js shape creation. The code uses `d3.select` to target the SVG element, reads its width and height attributes, and appends a circle with `svg.append('circle')`, setting its radius, center coordinates, fill color, and stroke. The example shows how D3 v5 manipulates SVG attributes directly to render a single geometric shape without data binding or interactivity, serving as an introductory exercise in the library’s core selection and append methods.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
