【问题描述】:
如果更新下面的代码以在版本 4 中工作,我们将不胜感激。我已将 zoom.behaviour 更改为 d3.zoom,但我不清楚需要进行的其他更改。它看起来比 v3 更复杂!

<p>Use the mouse to pan (click and move) / zoom (scrollwheel)</p>

<script type="text/javascript">
var svg = d3.select("body")
.append("svg")
.attr("width", "100%")
.attr("height", "100%")
.call(d3.zoom().on("zoom", function () {
svg.attr("transform", "translate(" + d3.event.translate + ")" + " scale(" + d3.event.scale + ")")
}))
.append("g")
svg.append("circle")
.attr("cx", document.body.clientWidth / 2)
.attr("cy", document.body.clientHeight / 2)
.attr("r", 50)
.style("fill", "#B8DEE6")
</script>
</html>
