{"version":"1.0","type":"rich","title":"Let's make a face with d3","description":"This example draws a single circle in an SVG, using D3 v5 to select the root `<svg>` element and append a `<circle>` shape. The circle’s radius is set to half the viewport height (250) and its center is placed at the middle of a 960×500 canvas. The code uses `d3.select`, `append`, and `attr` methods to position the shape, with a fixed `height` and `width` defined in JavaScript. No data source is used; the visualization is purely geometric and static.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/73a53af635b1459d9c2bfa2af45ca34b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
