Javascript 将过渡添加到可缩放的圆形填充

Javascript 将过渡添加到可缩放的圆形填充,javascript,d3.js,Javascript,D3.js,我在flare4.csv中有这些数据: SplitMth,id,value Dec,FRUIT, Dec,FRUIT~Apples, Dec,FRUIT~Apples~X,100 Dec,FRUIT~Pears, Dec,FRUIT~Pears~Y,200 Dec,FRUIT~Lemon, Dec,FRUIT~Lemon~Z,300 Jan,FRUIT, Jan,FRUIT~Apples, Jan,FRUIT~Apples~X,300 Jan,FRUIT~Pears, Jan,FRUIT~Pea

我在
flare4.csv
中有这些数据:

SplitMth,id,value
Dec,FRUIT,
Dec,FRUIT~Apples,
Dec,FRUIT~Apples~X,100
Dec,FRUIT~Pears,
Dec,FRUIT~Pears~Y,200
Dec,FRUIT~Lemon,
Dec,FRUIT~Lemon~Z,300
Jan,FRUIT,
Jan,FRUIT~Apples,
Jan,FRUIT~Apples~X,300
Jan,FRUIT~Pears,
Jan,FRUIT~Pears~Y,200
Jan,FRUIT~Lemon,
Jan,FRUIT~Lemon~Z,100
然后我有以下圆形包装可视化,这是对

现场预览:

我想做两件事,但我想第二件事需要另外一个问题

如何修改代码,以便当我从输入下拉列表中选择“Dec”时,可视化效果会相应地改变,并在单击缩放时表现出预期的效果

(我想将上述更改设置为5秒的过渡l
