var margin = {
top: 20,
right: 20,

  },
  svgWidth = 800,
  svgHeight = 500,
  width = svgWidth - margin.left - margin.right,
  height = svgHeight - margin.top - margin.bottom;

svg = d3.select('body')
  .append("svg")
  .attr("style", "width: " + svgWidth + "px\; height: " + svgHeight + "px\;");

var x = d3.scaleUtc().range([0, width])
  .domain([new Date("3/12/2017"), new Date("3/30/2017")]);

var y = d3.scaleBand()
  .range([height, 0])
  .padding(0.1)
  .domain(["test"])

var xAxis = d3.axisBottom(x)
  .tickFormat(d3.utcFormat("%m-%d"));

var yAxis = d3.axisLeft(y);
