Convert vertical stacked bar to horizontal stacked bar D3.js v4

Question

I found a vertical stack bar graph sample on google - http://bl.ocks.org/juan-cb/43f10523858abf6053ae I want to convert it in horizontal stacked bar graph. I have done the changes but something is wrong. Graph is not correct.I think all the bars are overlapped.

Please help me to resolve this. Code is copied.

A few minor things were missing/incorrect:

The group ( <g> ) containing the bars was being transformed incorrectly (I'm guessing you missed this while changing from vertical stacked to horizontal) ie the following line
```
 .attr("transform", function(d) { return "translate(" + y(d.rooms) + ",0)"; }); 
```
translates the bar groups from the left and the y position would be 0 and hence the overlap. I've changed that to this:
```
 .attr("transform", function(d) { return "translate(0, " + y(d.rooms) + ")"; }); 
```

The rects' x value is changed from x(d.y1) to x(d.y0) (might be a typo)

 bar_enter.append("rect") .attr("height", y.bandwidth()) .attr("x", function(d) { return x(d.y0); })

Axis padding was missing for the scaleBand(). I've added that (check docs for more info)
```
 var y = d3.scaleBand() .rangeRound([height, 0]).padding(0.1); 
```

Reset the margins to adapt to the SVG dimensions:

 var margin = {top: 10, right: 60, bottom: 60, left: 50},

Combining all of the above, here's a fork of your codepen:
