{"version":"1.0","type":"rich","title":"Fork of D3 Transitions","description":"A fork of D3 Transitions demonstrates coordinated enter, update, and exit animations for six colored circles. A slow two-second transition expands new circles from radius zero to their target sizes with staggered delays, while a fast 500-millisecond linear easing moves existing circles to new positions; removing circles shrinks them back to zero. The example uses D3's `transition()`, `transition.attr`, `selection.join`, and the `easeLinear` easing function to orchestrate the lifecycle. Each circle is rendered as an SVG element with a fixed fill color and partial opacity on a light green background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b395a62c85424b0cb0eb39c45e67cea0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
