D3js SVG vs DIV

JavaScript performance comparison

Test case created by Raul Fernandez

Info

Test performance using D3js library and building graphics using SVG elements (G, RECT) or DOM elements (DIVS)

      round = Math.round;
      random = Math.random;
   
      for (i; i < size; i += 1) {

        obj.x = round(maxRange * random());
        obj.y = round(maxRange * random());

    var dataSource = dataSourceGenerator(1000, 100);
   
    var divContainer = d3.select("#divContainer");
    var svgContainer = d3.select("#svgContainer");
