Is anyone able to offer an explanation of the change in relative size of the rect and text when adding attributes (width, height, viewBox) to the SVG element? (tested in Firefox 30 on Linux x86_64)

<tspan dy="1.69em" x="2.65em">QQQ</tspan>
</text>

</html>
shows as desired:
changing the svg element to
<svg width="400px" height="300px">
or
<svg width="400px" height="300px" viewBox="0 0 400 300">
gives this result:
See: http://www.impressivewebs.com/understanding-em-units-css/
If you do not set font-size anywhere in your document (css or html file), then "em" will be relative to the size of font used by the web browser.
In google chrome, this is in settings under: web content -> font-size.

It is basically 2 simple SVG object. The first one is a hand written just for the test and it is working:

The second is automatically generated and it is not working.

I have tried to simplified down the second one to see why is not working, but without luck. Anybody have an idea what could be the reason?
update1: The file can be opened in Safari and it is rendering both SVG image correctly. I have uploaded a screenshot here. The first SVG is the quarter circle, the second one is the number 1.
You've written the viewBox attribute as viewbox.
SVG and XHTML are case sensitive languages whereas HTML is not so if the EPUB importer is expecting XHTML then this will be a problem.
Most epub viewers that I'm familiar with use a web engine for rendering. So to get your SVG to be visible in an epub, it probably needs to be visible in a web browser.
Trying your second SVG, I don't see anything in Chrome or Firefox. Or in a generic image viewer.
If I add a stroke= value to your path, I see "something" in the browser, but it's a tiny little thing. As if the viewbox and/or the use settings are confusing the browser.
I'm new to d3js and trying to implement zoom and panning to a specific layer. While zooming the floorplan(attached image) the marker size also changes accordingly. Ideally the marker should change position with its fixed size based on panning or zoom level. I'm using below mentioned code. Any help is appreciated.

I'm using material designe icon in an svg format.
When I try to display the icon in my html I get the error:
"icon mdsize: A not found".
I saved all the icons in an svg file with all the paths.
My config.js file:
app.config(function($mdIconProvider){
$mdIconProvider.iconSet('mdsize', 'fileSrc', 24);
});
My svg file:
<g id="A">
<path d="iconPath" fill="none"/>
<path d="anotherPath"/>
</g>
My html:
<md-icon md-svg-icon="mdsize:A"></md-icon>
The md-icon tag is inside an md-list-item that is generated by ng-repeat.
Important to mention: There is another md-icon that is saved in the same svg file inside the md-list-item and it is shown on the html page. The way of presenting them is iddenticle so I don't see why the other icon won't show.
I don't know much about svg but I've had a play and this works without errors.

If I replace the content of fileSrc.txt with the following I also don't see any errors:

Note: These files work with Firefox but Chrome shows a "Cross origin" error.
I am working on using external svg groups marked by ID for initiation of event via mouseover initiator using SnapSVG library.

I really don't know what to do with it :/
I have an HTML page with a <base> tag, also containing SVG. Same-document references such as the below within the SVG then fail:
<html>
<head>
<base href="http://my/server/basedir">
</head>
<body>
<svg>
<g>
<path d="M100,100 L150,150" id="path"/>
<text>
<textpath xlink:href="#path"/>
</text>
</g>
</svg>
</body>
</html>
The xlink:href="#path" reference fails to resolve. This works fine without the HTML base element. It also works if I replace the href attribute on the textpath element with an absolute IRI followed by the fragment identifier.
It seems to me that SVG should treat same-document IRI's differently and independent of the HTML base. In http://www.w3.org/TR/xmlbase/#same-document it says "Dereferencing of same-document references is handled specially.", although granted that's in the context of xml:base. By the way, I played with putting an xml:base on the svg element in hopes of overriding the HTML base setting for couldn't figure out how to make that work.
Case 1: without xml:base
Works in IE(Edge),Chrome, but not Firefox.
<html>
<head>
<base href="http://my/server/basedir">
</head>
<body>
<svg width="300" height="300" xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink">
<g>
<path d="M100,100 L150,150" id="path"/>
<text>
<textpath xlink:href="#path">Hello</textpath>
</text>
</g>
</svg>
</body>
</html>
Case 2: with xml:base
Works in IE(Edge),Chrome, Firefox.
If this page url is http://my/thisfile.htm then set xml:base="http://my/thisfile.htm" on the svg tag or textpath tag.
<html>
<head>
<base href="http://my/server/basedir">
</head>
<body>
<svg width="300" height="300" xmlns="http://www.w3.org/2000/svg"
xmlns:xlink="http://www.w3.org/1999/xlink"
xml:base="http://my/thisfile.htm">
<g>
<path d="M100,100 L150,150" id="path"/>
<text>
<textpath xlink:href="#path">Hello</textpath>
</text>
</g>
</svg>
</body>
