{"version":"1.0","type":"rich","title":"HTML Starter","description":"This example presents three animated circle charts, each with its own dataset and button. Clicking a button cycles through data values, causing the corresponding circle’s radius to transition smoothly while its numeric label updates. The visualization uses D3 v4 with `d3.select`, `d3.scaleLinear` for mapping data to radius and color, and `transition().attr` to animate changes. Each circle’s fill shifts along a gradient, and buttons trigger the updates through custom click handlers.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2a35bfeeb6de4d63a9cf8868de7d3c61?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
