Elements added to SVG with D3 are not displayed

Question

I am trying to display some simple histograms with D3 where each column is divbut nothing is displayed.

var chartData =  [4, 8, 15, 16, 23, 42];
var body = d3.select('body');
    	
var svg = body.append('svg')
   .attr("width",800)
   .attr("height",500);
    				
var div = svg.append('div').attr('class', '.chart');
    	
for (var i = 0; i < chartData.length; i++) {
   div.append('div')
    	.attr("height", 20)
    	.attr("width", chartData[i]*10)
    	.html(chartData[i]);
}

.chart div {
	font: 10px sans-serif;
  background-color: steelblue;
	text-align: right;
	padding: 3px;
  margin: 1px;
	color: white;
}

When using SVG validation, I see newly created elements, and svg is highlighted, but the internal one divis not.

In short: you cannot add an HTML element to SVG. The reason is simple: <div>, <p>, <h1>, <h2>, <td>, <li>, etc. Not valid SVG elements.

, <div> SVG. console.log, SVG:

var svg = d3.select("svg");

var data = d3.range(5);

var divs = svg.selectAll("foo")
	.data(data)
	.enter()
	.append("div")
	.html("Where are you?")
	
var mySVG = (new XMLSerializer()).serializeToString(svg.node());
console.log(mySVG)
