<HTML>
   <head>
      <script type = "text/JavaScript" src = "https://d3Js.org/d3.v4.min.Js"></script>
      <style>
         svg text {
            fill: purple;
            Font: 12px sans-serif;
            text-anchor: end;
         }
      </style>
   </head>

   <body>
      <script>
         var wIDth = 400, height = 400;
         var data = [100, 120, 140, 160, 180, 200];
         var svg = d3.select("body")
            .append("svg")
            .attr("wIDth", wIDth)
            .attr("height", height);

         var xscale = d3.scalelinear()
            .domain([0, d3.max(data)])
            .range([0, wIDth - 100]);

         var yscale = d3.scalelinear()
            .domain([0, d3.max(data)])
            .range([height/2, 0]);

         var x_axis = d3.axisBottom().scale(xscale);

         var y_axis = d3.axisleft().scale(yscale);

         svg.append("g")
            .attr("transform", "translate(50, 10)")
            .call(y_axis);

         var xAxisTranslate = height/2 + 10;

         svg.append("g")
            .attr("transform", "translate(50, " + xAxisTranslate  +")")
            .call(x_axis)
      </script>
   </body>
