Answer 1

SVG is a vector graphics text files format, based on XML standard ( as HTML ). So, it's a 'Markup Language' graphics oriented...
In HTML, the <svg> tag element is a container for inserting this format inline... ( you can do also standalone svg files, which can be refered with the 'src' attribute of <img> tag element, as others bitmaps file format gif, jpg, png )
