{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation and animation with D3.js by constructing a smiley face from SVG shapes and animating its eyebrows. A yellow circle forms the head, with eyes, rectangular eyebrows, and an arc-based mouth positioned using D3 selections and attribute setters. The code uses d3.select, d3.arc, and chained transitions with .transition().duration() to move the eyebrow group up and down over two 2-second cycles. All elements are appended to an SVG container, with positioning handled via transform attributes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/73fe7e382eef413497a60e293b3bb7de?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
