我正在尝试建立一个'clickToZoom'函数。在节点单击时，视图应该关注被单击的节点。event.transform对象返回{k, x, y}。到目前为止，我认为我可以从被单击的节点接收这些值并设置svg.attr("transform", "newValues")，我确实这样做了。显然它不像预期的那样工作。
景色确实改变了，但似乎重新设定了。

var width = window.innerWidth,
            height = window.innerHeight;

        var svg = d3.select("body").append("svg")
            .attr("width", width)
            .attr("height", height)
            .call(d3.zoom().on("zoom", function (event) {
                svg.attr("transform", event.transform)
                console.log(event.transform)
            }))
            .append("g")
