{"version":"1.0","type":"rich","title":"Fork of D3 Transitions","description":"Six circles in a pale green SVG canvas demonstrate D3's built-in transition system. On load, each circle animates from a radius of zero to its target size with a staggered delay, while subsequent updates move them instantly to new positions and exits shrink them back to nothing. Using D3 v7.8.5, the code employs `select` joins with `.data()` keys, `transition()` for both slow and fast timing, and `easeLinear` for uniform motion. Circle positions, radii, and hex colors are hardcoded in the data array.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"","width":960,"height":500,"cache_age":3600}
