{"version":"1.0","type":"rich","title":"let's make face with d3.js","description":"This example draws a smiling face on an SVG canvas using D3.js version 7. The code creates a yellow circle for the head, two circles for eyes, rectangles for eyebrows, and a path arc for the mouth, all positioned using absolute coordinates within a 960×500 viewport. It uses D3’s `select`, `append`, and `attr` methods to build and style the SVG elements, and the `arc` generator to define the mouth’s curved shape. The rendering is entirely vector-based, with no external data source.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/00094c63366e489bb5bc5cb39638ae19?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
