我正在试用这个example动画单词云，使用jasondavies's d3.layout.cloud。
它可以在d3版本3下运行，但是如果你用上面的任何版本更新它，它就不能正确显示了。你仍然可以看到一些单词的转换，但是其他的单词仍然在中间，没有缩放。
我把代码放在这里作为参考。

return {

//Some sample data - http://en.wikiquote.org/wiki/Opening_lines
var words = [
"You don't know about me without you have read a book called The Adventures of Tom Sawyer but that ain't no matter.",
"The boy with fair hair lowered himself down the last few feet of rock and began to pick his way toward the lagoon.",
"When Mr. Bilbo Baggins of Bag End announced that he would shortly be celebrating his eleventy-first birthday with a party of special magnificence, there was much talk and excitement in Hobbiton.",
"It was inevitable: the scent of bitter almonds always reminded him of the fate of unrequited love."

//Prepare one of the sample sentences by removing punctuation,
// creating an array of words and computing a random size attribute.
function getWords(i) {
return words[i]
.replace(/[!\.,:;\?]/g, '')
.split(' ')
.map(function(d) {
return {text: d, size: 10 + Math.random() * 60};
})
}
//This method tells the word cloud to redraw with a new set of words.
//In reality the new words would probably come from a server request,
// user input or some other source.
function showNewWords(vis, i) {
i = i || 0;
vis.update(getWords(i ++ % words.length))
setTimeout(function() { showNewWords(vis, i + 1)}, 2000)
}
//Create a new instance of the word cloud visualisation.
var myWordCloud = wordCloud('body');
//Start cycling through the demo data
showNewWords(myWordCloud);
</script>注意：我将示例中的填充颜色编辑为黑色。如果您想在d3 v4或更高版本中使用原始调色板，则需要使用var fill = d3.scaleOrdinal(d3.schemeCategory10)

好吧，我做了一些挖掘，他们基本上合并了进入和更新功能到一个使用
merge从版本v4开始。因此，要使上述功能正常工作，您必须替换
