{"version":"1.0","type":"rich","title":"Let's make a face with D3.js!","description":"This example demonstrates fundamental DOM manipulation with D3.js by building a smiley face from an SVG circle. Using the `select`, `append`, and `attr` methods from d3-selection, it sets the circle’s radius to half the SVG height and centers it via the `cx` and `cy` attributes. The code reads the SVG’s `height` and `width` attributes directly from the DOM, and runs against d3.v5 in a minimal HTML page with external styles defining the body margin and overflow. The face is static, with no interactive or animated features beyond the initial rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/53d77b0346024cf29190d9c3f83444e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
