{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This example displays a single circle positioned at coordinates (300, 300) with a radius of 40 pixels, filled with a teal color. The visualization uses an SVG element created with D3.js v4, where the circle is appended to a group that supports zooming and panning through the `d3.zoom` API. The viewport fills the browser window, and the circle remains stationary apart from user-driven transformations. The code relies on `d3.select` to bind the SVG to a div container, with styling applied via external CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/64c07b66c7c243ad82751a0e3ef7d200?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
