| Data Formats | SVG data is specified using many different micro-syntaxes such as Path Data Syntax and Polyline/Polygon Points List |
| Path Data Syntax | |
| Polyline/Polygon Points List | The points attribute is used to specify line paths for "<polyline>" and "<polygon>" |
| Elements: Basic Shapes | |
| "<circle>" | Creates a circle centered on cx, cy, with radius r |
| "<ellipse>" | Creates an ellipse centered on cx, cy, with radius rx and ry |
| "<line>" | Creates a line between two points, using the x1, y1, x2, and y2 attributes |
| "<path>" | Defines a shape using a path, which can include straight lines, curves, and sub-paths |
| "<polygon>" | Creates a closed polygon with straight lines between the points, using the points attribute |
| "<polyline>" | Creates a set of connected straight line segments, using the points attribute |
| "<rect>" | Creates a rectangle with the top-left corner at (x, y) and the specified width and height, optionally with rounded corners |
| Elements: Masking and Clipping | |
| "<mask>" | Defines a mask, which is used to apply image-based visibility to graphical elements |
| "<clipPath>" | Defines a clipping path, which is used to clip the rendering of other elements using paths and shapes |
| Elements: Painting | |
| "<linearGradient>" | Defines the paint server for a linear gradients |
| "<radialGradient>" | Defines the paint server for a radial gradients |
| "<pattern>" | Defines a paint server containing a repeated pattern, which is tiled to fill the area |
| "<stop>" | Defines a color stop for a gradient |
| "<marker>" | Creates a marker element that can be used to define graphical objects that can be used repeatedly in a drawing, such as arrowheads or other markers on paths |
| Elements: Structural | |
| "<svg>" | The root element of an SVG document |
| "<g>" | Creates a group of elements which can be transformed as a single object |
| "<defs>" | Container for definitions of reusable graphics elements |
| "<use>" | Reuses an existing element by referencing it with a URI |
| "<symbol>" | Defines a symbol element that can be used to define graphical templates which are not rendered directly but can be instantiated by a "<use>" element |
| <symbol> Usage: Coordinate System and Sizing Behavior | |
| CompileTimeMap usage examples | |
| "<text>" | Defines a graphics element consisting of text |
| "<tspan>" | The <tspan> element defines a sub-string or sub-group of text that can be independently positioned or styled inside an SVG text flow |
