The Basic SVG Tags
This section provides a basic overview of a subset of the SVG specification. Because it is next to impossible to condense a 600-page technical specification (http://www.w3.org/2000/svg) into 10 pages, this section describes a set of core concepts around the following types of SVG elements:
Structural elements
Basic shape and path elements
Textual elements
Linking elements
Several more-complex or less frequently used topics are not covered here, such as:
Gradients and filters
Embedded font glyph data
Clipping and masking
Color management
All of the elements have a set of common attributes that are not
necessarily listed in the attribute charts. For example, any element
can be given a unique identifier (so that it can be referenced by
scripts or hyperlinks). This identifier is assigned with the id attribute:
<!-- Define an arced path -->
<path id="path1"
d="M50,200 A150,150 0 1,0 350,200"
fill="none" stroke="black" />
<!-- Reference a previously defined path -->
<textPath xlink:href="#path1">Some text on a path</textPath>Most elements have additional attributes that describe optional language space and style attributes. These attributes are indexed in the SVG specification. For a more complete introduction to SVG, read SVG Essentials by J. David Eisenberg (O’Reilly).
Structural Tags
The structural tags define the basic building blocks of an SVG document: the top-level viewport, groups, definition blocks, and tags for labeling sections of code.
Example 6-1 draws four brightly ...
