{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates how to build a simple animated smiley face using D3.js. It shows a yellow circle with eyes, eyebrows, and a mouth, all constructed through fundamental DOM manipulation. The code uses `d3.select` to target the SVG element, `d3.append` to create shapes, and a chained `d3.transition` sequence to animate the eyebrows moving up and down over two-second intervals. The mouth is drawn as an arc using `d3.arc` with specified inner and outer radii. The rendering is SVG-based, with all elements positioned relative to the center of the canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/902ce571dc334e57b8ec60542629e3cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
