{"version":"1.0","type":"rich","title":"basic circles d3","description":"This example shows a simple D3.js visualization of seven semi-transparent circles in different colors and sizes on a light green background. The code demonstrates the D3 general update pattern and method chaining by selecting an SVG element, binding an array of circle data objects, and using the `join()` method to create circle elements. Each circle’s position, radius, and fill color are set via attribute functions. The example uses `d3.select` and `selectAll` with a hot-reload-friendly structure intended for tutorial purposes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/656fa9c4668f42a9b73c159157f2945a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
