{"version":"1.0","type":"rich","title":"smiley d3","description":"This example demonstrates a minimal D3 version 6 setup using an SVG canvas to draw a large yellow circle that fills the viewport, centered at half the width and height of the 960×500 SVG element. The code selects the SVG with `d3.select`, reads its dimensions via `attr`, and appends a circle with `append('circle')`, setting radius, coordinates, and fill color. It relies on D3’s selection and attribute methods to position the shape, serving as a basic introduction to D3’s declarative graphics in a static, single-element visualization.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b8dac1e7acd48f99b66c14ba5187487?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
