{"version":"1.0","type":"rich","title":"Smiley face with d3.js!!","description":"This example shows a stylized smiley face built from basic SVG shapes—circles for the head and eyes, a line for an eyebrow, and an arc for the mouth—all rendered inside a React component. The face is centered using a `<g>` transform, with sizes and positions derived from computed constants like `eyeOffsetX` and `mouthRadius`. It uses React 16.9 with ReactDOM to mount the SVG, while the mouth arc is generated with D3’s `arc()` function, specifying inner and outer radii plus start and end angles. The code also includes an ellipse and an extra line that are not visually connected to the main composition.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3623da85b6b54afcbc56c9c1773f9f19?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
