Javascript d3单词云-单词超出范围

您必须减小单词字体大小,以确保单词适合svg或增加svg的大小。将文本锚属性设置为开始,并在translate方法中对d.x值使用Math.abs()将有所帮助 将留下以下内容作为绘图功能:
function draw(words) {
d3.select("#d3").append("svg")
.attr("width", 800)
.attr("height", 300)
.attr("class", "wordcloud")
.append("g")
// without the transform, words words would get cutoff to the left and top, they would
// appear outside of the SVG area
.attr("transform", "translate(370,155)")
.selectAll("text")
.data(words)
.enter()
.append("text")
.style("-webkit-text-stroke-width", "1px")
.style("-webkit-text-stroke-color", "black")
.style("font-size", function(d) { return d.size + "px"; })
.style("fill", function(d, i) { return color(i); })
.attr("text-anchor", "start")
.attr("transform", function(d) {
return "translate(" + [Math.abs(d.x), d.y] + ")rotate(" + d.rotate + ")";
})
.text(function(d) { return d.text; })
.on("click", function (d, i){
window.open(d.url, "_self");
});
}此实现没有任何强制要求,即所有内容都保持在提供的大小内。你必须使画布变大,字体变小或减少字数。
