D3 donut chart text centering

Question

I'm using a d3 donut chart for a project and I'm having issues centering the text inside the donut. I found a piece of code that I have modifying, but frankly I don't understand it much.

I have added the text in the center, but it's not quite centered. Is there anyone that could help me center it? I tried adding 'margin-top' to bring it down but that doesn't work, nor do a lot of css things I tried.

Here's the specific part that attaches the text:

 svg.append("text")
       .attr({
         "text-anchor": "middle",
       }).style({'fill': 'red', 'font-size': '18px'}).text(calories);
};

Answer 1

You may have noticed that two labels outside the circle are vertically centered, but the one in the middle is not.

It is missing following line:

 .attr('dy', '0.35em')

This is the new codepen.

I will leave to you to discover why is that line magical.
