{"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 building a smiling face whose eyebrows move up and down. It uses D3’s `select` and `append` to create SVG circles, rectangles, and a path for the mouth, with the mouth drawn via the `arc` generator. The animation relies on chained `transition` and `duration` calls to shift the eyebrow group’s transform attribute. The code imports named methods from the d3 module and sets attributes like `r`, `cx`, and `d` directly on SVG elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8680ea5fd4584c45850d2f5c30c2c7f1?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
