D3 Chart SVG响应条和轴

Question

我已经逐步创建了D3图表。我做了一些更改以使SVG响应。我现在的目标是使条形图更具响应性，以便在屏幕尺寸较小（宽度）时更容易阅读。我已经粘贴了下面和页面底部的片段，我专注于我认为解决方案被隐藏的部分。

var data = [
    "area": "one ", "value": 18000,
    "area": "Two ", "value": 17000,
    "area": "three ", "value": 80000,
    "area": "four ", "value": 55000,
    "area": "five ", "value": 100000,
    "area": "six", "value": 50000,
    "area": "seven", "value": 50000
];
 
  
var margin = top: 10, right: 10, bottom: 70, left: 30;
var width = 1900 - margin.left - margin.right;
var height = 400 - margin.top - margin.bottom;
          

//A fully-responsive chart area
var svg = d3.select("#chart-div")
                .append("svg")
                .attr("width","100%")
                .attr("height","500px")
                .attr("viewBox","0 0 "+
                    (width+margin.left+margin.right)+
                    " "+
                    (height+margin.top+margin.bottom) )
                .append("g")
                .attr("transform","translate("+
                    margin.left+","+margin.top+")");

var tooltip = d3.select("body").append("div").attr("class", "toolTip");
  
var x = d3.scaleLinear().range([0, width]);
var y = d3.scaleBand().range([height, 0]);

var g = svg.append("g")
		.attr("transform", "translate(" + margin.left + "," + margin.top + ")");


  	data.sort(function(a, b)  return a.value - b.value; );
  
  	x.domain([0, d3.max(data, function(d)  return d.value; )]);
    y.domain(data.map(function(d)  return d.area; )).padding(0.1);

    g.append("g")
        .attr("class", "x axis")
       	.attr("transform", "translate(0," + height + ")")
      	.call(d3.axisBottom(x).ticks(5).tickFormat(function(d)  return parseInt(d / 1000); ).tickSizeInner([-height]));

    g.append("g")
        .attr("class", "y axis")
        .call(d3.axisLeft(y));

    g.selectAll(".bar")
        .data(data)
      .enter().append("rect")
        .attr("class", "bar")
        .attr("x", 0)
        .attr("height", y.bandwidth())
        .attr("y", function(d)  return y(d.area); )
        .attr("width", function(d)  return x(d.value); )
        .on("mousemove", function(d)
            tooltip
              .style("left", d3.event.pageX - 50 + "px")
              .style("top", d3.event.pageY - 70 + "px")
              .style("display", "inline-block")
              .html((d.area) + "<br>" + "£" + (d.value));
        )
    		.on("mouseout", function(d) tooltip.style("display", "none"););

.svg-container 
    display: inline-block;
    position: relative;
    width: 100%;
    padding-bottom: 100%; /* aspect ratio */
    vertical-align: top;
    overflow: hidden;

.svg-content-responsive 
    display: inline-block;
    position: absolute;
    top: 10px;
    left: 0;

<script src="https://d3js.org/d3.v4.min.js"></script>
<div id="chart-div" style="width:100%;height:100%;"></div>

我用以下代码更改了部分代码：

var parentwidth = $("#chart-div").parent().width(); 
var margin = top: 10, right: 10, bottom: 70, left: 30;
var width = parentwidth - margin.left - margin.right;
var height = 400 - margin.top - margin.bottom;

我实际上使用jQuery获取parentwidth。

我其实在想是否：

a）在这种情况下可以避免使用jQuery。

b）理想情况下，使条形按比例缩放，以便用户可以轻松读取所有内容（小文本大小是个问题）：

我正在测试下面的函数，但我可能会收到与某些chrome插件有关的错误，以避免交叉来源错误。如果以下是最佳解决方案，我可以更新问题：

function resize() 
  var width = parseInt(d3.select("#chart").style("width")) - margin.left - margin.right,
  height = parseInt(d3.select("#chart").style("height")) - margin.top - margin.bottom;

  // Update the range of the scale with new width/height
  xScale.range([0, width]);
  yScale.rangeRoundBands([height, 0], 0.1);

  // Update the axis and text with the new scale
  svg.select(".x.axis")
    .call(xAxis)
    .attr("transform", "translate(0," + height + ")")
    .select(".label")
      .attr("transform", "translate(" + width / 2 + "," + margin.bottom / 1.5 + ")");

  svg.select(".y.axis")
    .call(yAxis);

  // Update the tick marks
  xAxis.ticks(Math.max(width/75, 2), " $");

  // Force D3 to recalculate and update the line
  svg.selectAll(".bar")
    .attr("width", function(d)  return xScale(d["total"]); )
    .attr("y", function(d)  return yScale(d["Name"]); )
    .attr("height", yScale.rangeBand());
;
