{"version":"1.0","type":"rich","title":"first try","description":"This visualization is a simple smiley face drawn from SVG primitives: a yellow circle, two black eyes, and a curved mouth path. The face is centered in an SVG canvas, with all elements grouped and positioned using affine transforms. The code uses the D3 `select` API to query the SVG element and `append` to add shapes, while the mouth is generated with the `d3.arc` function, which produces an SVG path from polar coordinates. The example demonstrates basic D3 v7 SVG construction without data binding.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/aa9187b938764ff6b06c620211d5eaa6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
