{"version":"1.0","type":"rich","title":"Let's make a face with D3.js","description":"A yellow smiley face drawn with D3.js appears centered on a dark background, with circular eyes, rectangular eyebrows, and a curved mouth built from an arc path. The example demonstrates SVG shape creation and animation using d3-selection and d3-arc, as the eyebrows transition vertically twice via chained `transition().duration()` calls. The face is constructed from fixed numeric constants for spacing and dimensions, rendered inside an SVG element sized 960 by 500 pixels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b342a2c138ca45f886bc487a37677315?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
