{"version":"1.0","type":"rich","title":"learning","description":"This example displays seven semi-transparent circles of varying sizes and bright colors on a pale green background, each positioned at distinct coordinates. The visualization uses D3’s `select`, `selectAll`, and `join` methods within `index.js` to bind an array of hardcoded objects—containing `x`, `y`, `r`, and `fill` values—to SVG circle elements. The code sets the background via a styled `svg` element and applies a fixed opacity of 0.708 to all circles. It serves as a simple, editable template, inviting users to fork and customize the theme.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/670add63b566459eafc4c7ce01792d95?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
