代码示例1
var margin = {top: 50, right: 20, bottom: 20, left: 60},
    dynwidth = $("#nairobistock").width(),
    rowheight = 460;
    width = dynwidth - margin.left - margin.right,
    height = rowheight - margin.top - margin.bottom;

var projection = d3.geo.mercator()
    .center([36.8, -1.3])
    .scale([90000])
    .translate([width/2, height/2]);

var nairobipathing = d3.geo.path().projection(projection);

var svg = d3.select("#nairobistock").append("svg")
    .attr("width", (width + margin.left + margin.right) )
    .attr("height", (height + margin.top + margin.bottom) );

d3.json("topojson/KEN-3topo.json", function(error, nairobi){
    if (error) return console.error(error);
    console.log(nairobi);
    console.log("topojson added");

    svg.selectAll("path")
        .data(topojson.feature(nairobi, nairobi.objects.suburbs).features)
        .enter()
        .append("path")
        .attr("class", function(d) {return d.ID;})
        .attr("d", nairobipathing );

});
