Caption an SVG with <text> element?

I am new to working with SVGs. I am trying to caption an svg of a person with that person's name. Here is my attempt:
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
viewBox="0 0 258.75 258.75" style="enable-background:new 0 0 258.75 258.75;" xml:space="preserve">
<g>
<circle cx="129.375" cy="60" r="60"/>
<path d="M129.375,150c-60.061,0-108.75,48.689-108.75,108.75h217.5C238.125,198.689,189.436,150,129.375,150z"/>
<text text-anchor="middle" x="60" y="75">Person Name Here</text>
</g>
</svg>
When I try to anchor the text below the image the text disappears. how do I
Change the size of the image?
Leave space at the bottom of the image for the person's name?
Here is the snippet:
var svg = '<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"viewBox="0 0 258.75 258.75" style="enable-background:new 0 0 258.75 258.75;" xml:space="preserve"> <g> <circle cx="129.375" cy="60" r="60"/><path d="M129.375,150c-60.061,0-108.75,48.689-108.75,108.75h217.5C238.125,198.689,189.436,150,129.375,150z"/><text text-anchor="middle" x="60" y="75">Person Name Here</text></g></svg>'
$('#name').append(svg);
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<p id="name">Hello</p>

This may be what you need:
You can change the size of the image with css, it will scale all your svg.
You just need to give some more space to the viewBox and position your name accordingly.
Hope this helps, snippet:
var svg = '<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"viewBox="0 0 258.75 350.75" style="enable-background:new 0 0 258.75 258.75;" xml:space="preserve"> <style>.style1 {font-size: 15px;} </style> <g> <circle cx="129.375" cy="60" r="60"/><path d="M129.375,150c-60.061,0-108.75,48.689-108.75,108.75h217.5C238.125,198.689,189.436,150,129.375,150z"/><text class="style1" text-anchor="middle" x="125" y="290">Person Name Here</text></g></svg>'
$('#name').append(svg);
svg, object {
width: 200px;
}

<p id="name">Hello</p>

Animate bar visible only on circle - svg

How to make this animated green bar visible only on circle?

Link to CodePen

With a clipPath you can create a mask.
you have a to create a <circle> inside a <defs> tag( it doesn't render element inside it and make it accessible )
you have to create a clipPath thate takes sizes and position from the circle using <use xlink:href="#circleID"...
you should add the attribute clipPath="url(#clipPathID)" to any element or group of element you want to mask.

Just edited to show the animated element just inside the black fill of your circles. The process is the same of the previous example, but now The shape of the mask path has been created copying the d=".." attribute value from both black circles:

How to access an svg inner id and have CSS change the fill color of that id?

This is my svg file
next.svg
<?xml version="1.0" encoding="utf-8"?>
<?xml-stylesheet type="text/css" href="style.css"?>
<!DOCTYPE svg PUBLIC "-//W3C//DTD SVG 1.1//EN" "http://www.w3.org/Graphics/SVG/1.1/DTD/svg11.dtd">
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 100 100" enable-background="new 0 0 100 100" xml:space="preserve">
<g class="next">
<g>
<polygon fill="#FFD92D" class="inner" points="20.587,5.055 78.706,48 20.587,90.945"/>
<path fill="#FF9900" class="outer" d="M21.623,7.11L76.961,48L21.623,88.89V7.11 M19.55,3v90l60.9-45L19.55,3L19.55,3z"/>
</g>
</g>
</svg>
This is my basic html to display the svg
<div>
<object id="objsvg" class="svgbtn" type="image/svg+xml" data="next.svg" onclick="changeSVGColor()"></object>
</div>
This is my style.css file
.inner {
fill: #000000;
}
.inner-new-color {
fill: #ff00ff;
}
This is my basic jQuery to change the color of .inner in svg file. What am I doing wrong?
It does not even seem like the #objsvg selector has the inner class at all, since $("#objsvg").hasClass("inner")); returns false.
function changeSVGColor() {
$("#objsvg").removeClass("inner");
$("#objsvg").addClass("inner-new-color");
}

Select the portion you want to change by class. $(".inner")
$(".inner").removeClass("inner").addClass("inner-new-color");
Example Fiddle

The ID will not work on the parent or 'object', you will need to open your SVG with something like sublime text, and add an id="objsvg" for whatever path you are trying to manipulate.
e.g..
<svg version="1.1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px" viewBox="0 0 100 100" enable-background="new 0 0 100 100" xml:space="preserve">
<g class="next">
<g>
<polygon fill="#FFD92D" class="inner" points="20.587,5.055 78.706,48 20.587,90.945"/>
<path id="objsvg" fill="#FF9900" class="outer" d="M21.623,7.11L76.961,48L21.623,88.89V7.11 M19.55,3v90l60.9-45L19.55,3L19.55,3z"/>
</g>
</g>
</svg>

After dynamically adding element to SVG the item is not visible

I am creating a custom map that is drawn in an SVG. I want to add a polygon to this map,
however after adding the polygon it is not drawn. If I paste the complete page into an .html file and open it, it does show (http://peterelzinga.eu/map/test.html).
The code for adding the polygon to my SVG:
var svg = file_get_contents("18/135160/86183.svg");
var parser = new DOMParser();
var data = parser.parseFromString(svg, "text/xml");
data = data.firstChild;
console.log(data);
data.setAttribute ("x", d);
data.setAttribute ("y", e);
document.getElementById('front').appendChild(data);
The SVG element after adding the polygon:
<svg id="map" xmlns="http://www.w3.org/2000/svg" version="1.1" width="512" height="512">
<g id="back">
<image xlink:href="12/2110/1345.png" x="0" y="0" width="256" height="256"></image>
</g>
<g id="front">
<g width="256" height="256" x="0" y="0">
<polyline fill="#FFFFFF" stroke="#000000" stroke-miterlimit="10" points="256,85.333 209,100.667 230.334,158.334 143,194.334 160.667,248.667 221.667,223.667 256,241.334 " onclick="alert('St Jansdal')"></polyline>
</g>
</g>
</svg>
Does anyone know why this happens?

From Mozilla docs: https://developer.mozilla.org/en-US/docs/Web/API/DOMParser
You should specify the content type as "image/svg+xml" to get a SVGDocument.
The problem is that your generated nodes are not SVG nodes, but XML nodes.
I had a similar problem solved by switching from createElement to createElementNS. See answer: jquery's append not working with svg element?

Why the above won't work is still a mistery to me. However, i did manage to resolve the problem by using the following solution:
The javascript function to load and add an new svg element - which contains our polyline - to the main element:
var api = new XMLHttpRequest;
api.open("GET", a+"/"+b+"/"+c+".svg", false);
api.send("");
if( api.status == 200 ) {
var parser = new DOMParser();
var data = parser.parseFromString(api.responseText, "text/xml");
data = data.firstChild;
console.log(data);
data.setAttribute("x", d);
data.setAttribute("y", e);
document.getElementById('front').appendChild(data);
}
Now instead of only having the polyline element in the .svg file, I have put a complete svg element in the file:
<svg version="1.1" id="Layer_1" xmlns="http://www.w3.org/2000/svg" xmlns:xlink="http://www.w3.org/1999/xlink" x="0px" y="0px"
width="256px" height="256px" viewBox="0 0 256 256" enable-background="new 0 0 256 256" xml:space="preserve">
<polyline fill="#FFFFFF" points="0,97 45,81.333 51.667,100.667 13.667,117.333 31,164 142.167,119.5 127.167,75.001
172.667,53.341 152.5,0 0,0 "/>
</svg>
And this does work. By setting the X and Y values of the I can position the svg in the correct spot so the polyline is drawn in the right place.
The endresult:
<svg id="map" xmlns="http://www.w3.org/2000/svg" version="1.1" width="512" height="512">
<g id="back">
<image xlink:href="18/135160/86183.png" x="0" y="0" width="256" height="256"></image>
