并使用以下代码生成条形图

var margin = {top: 20, right: 20, bottom: 70, left: 40},
width = 800 - margin.left - margin.right,
height = 400 - margin.top - margin.bottom;

var parseDate = d3.timeParse("%Y-%m-%d");

var x = d3.scaleBand().range([0, width]);

var y = d3.scaleLinear().range([height, 0]);

var xAxis = d3.axisBottom(x);

var yAxis = d3.axisLeft(y);

var tip = d3.tip()
.attr('class', 'd3-tip')
.offset([-10, 0])
.html(function(d) {
return "<strong>Month of " + d.date + ":</strong> <span style='color:red'>" + d.value …
