{"version":"1.0","type":"rich","title":"prac1","description":"This example shows a blank slate starting point for the VizHub V3 runtime, displaying a single fixed circle on an SVG canvas. The code uses `d3.select` and `selectAll` with a data join to create an SVG element sized to the container's dimensions, then binds a one-element dataset to render a circle at coordinates (316, 231) with a radius of 86. The static visualization demonstrates the minimal setup required for the runtime, which supports hot reloading and interactive widget adjustments.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2fee8b2f185b479bbc8eb44a55b4144e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
