Javascript D3根据需要隐藏节点

我正在寻找一种根据节点集中的变量显示和隐藏节点的简单方法

我有3个复选框FTSE 100 FTSE 250 FTSE ALL Share，我的节点有一个可变索引，即FTSE 100、250、allshare，因此每当用户选择FTSE 100时，我只想显示具有FTSE索引的节点，以此类推，并显示其余复选框选项

数据示例：

var dataset = {"nodes":[{"fullName":"Ultra Electronics Holdings plc","index":"FTSE 250"},{"fullName":"Unilever PLC","index":"FTSE 100"},{"fullName":"United Utilities Group PLC","index":"FTSE 100"},{"fullName":"Victrex plc","index":"FTSE 250"},{"fullName":"Vectura Group plc","index":"FTSE 250"},{"fullName":"Vp plc","index":"FTSE All-Share"},{"fullName":"VPC Specialty Lending Investments Plc","index":"FTSE All-Share"},{"fullName":"Wincanton plc","index":"FTSE All-Share"},{"fullName":"Workspace Group plc","index":"FTSE 250"},{"fullName":"William Hill plc","index":"FTSE 250"},{"fullName":"Witan Pacific Investment Trust PLC","index":"FTSE All-Share"},{"fullName":"Worldpay Group plc","index":"FTSE 100"},{"fullName":"Witan Investment Trust plc","index":"FTSE 250"},{"fullName":"Whitbread PLC","index":"FTSE 100"},{"fullName":"Worldwide Healthcare Trust PLC","index":"FTSE 250"},{"fullName":"Xaar plc","index":"FTSE All-Share"},{"fullName":"Zoopla Property Group Plc","index":"FTSE 250"}],"edges":[{"source":0,"target":68,"officers":["PARKER, Thomas, Sir"]},{"source":0,"target":147,"officers":["STEVENS, Anne"]},{"source":0,"target":286,"officers":["PARKER, Thomas, Sir"]},{"source":0,"target":341,"officers":["GROTE, Byron"]},{"source":0,"target":363,"officers":["GROTE, Byron"]},{"source":1,"target":2,"officers":["ABERDEEN ASSET MANAGEMENT PLC","YOUNG, Hugh"]},{"source":1,"target":7,"officers":["GILBERT, Martin","YOUNG, Hugh"]},{"source":1,"target":23,"officers":["ABERDEEN ASSET MANAGEMENT PLC"]},{"source":1,"target":67,"officers":["YEA, Philip"]},{"source":1,"target":98,"officers":["ABERDEEN ASSET MANAGEMENT PLC"]},{"source":1,"target":102,"officers":["ABERDEEN ASSET MANAGEMENT PLC"]},{"source":1,"target":150,"officers":["YEA, Philip"]},{"source":1,"target":254,"officers":["ABERDEEN ASSET MANAGEMENT PLC"]},{"source":1,"target":255,"officers":["ABERDEEN ASSET MANAGEMENT PLC"]}]};

d3代码呢

var w = 1200;
var h = 800;

var viewBoxX = 0, viewBoxY = 0;

var force = d3.layout.force()
             .nodes(dataset.nodes)
             .links(dataset.edges)
             .size([w, h])
             .linkDistance([100])
             .charge([-240])
             .gravity(0.07)
             .start();

var colors = d3.scale.category10();

var svg = d3.select("#networkGraph")
            .append("svg")
            .attr("width", w)
            .attr("height", h)
            .attr("viewBox", "0 0 "+w+" "+h);

svg.append('rect')
              .classed('bg', true)

                .style("stroke-width", function(d){return officersScale(d.officers.length);});
    var edgeText = container.selectAll(".edge")
                .append("text")
                .attr("dy", ".35em")
                .each(function(d){
var officers = ''; 
                                for (index = 0; index < d.officers.length; ++index) {
                                    d3.select(this).append("tspan")
                                        .text(d.officers[index])
                                        .attr("dy", index ? "1.2em" : 0)
                                        .attr("text-anchor", "middle")
                                        .attr("x", 0);
                                }
                            });

var node = container.selectAll(".node")
    .data(dataset.nodes)
    .enter()
    .append("g")
    .attr("class", "node")
    .call(force.drag);

node.append("circle")
    .attr("r", 15)
    .style("fill", function(d,i){ 
    return colors(i)
        })
    .call(force.drag);

node.append("text")
    .attr("dx", 0)
    .attr("dy", "0.35em")
    .attr("font-weight", 600)
    .attr("text-anchor", "middle") 
    .style("pointer-events", "none") 
    .text(function(d){ return d.name});

HTML位：
