Basic Mark

Basic marks in VGrammar describe a specific type of drawing shape.

Group Mark (Group)

Group mark are used to group multiple primitives for unified operations such as scaling and translation. The graphic type is declared as 'group'.

It should be noted that group mark is different from other basic marks and do not support data mapping. A declared Group Mark can only correspond to a single final group graphic element.

Rectangle Mark (Rect)

Rectangle mark is used to draw rectangles and can create visualization effects such as bar charts. The graphic type is declared as 'rect'.

Rendering example of rectangle mark:

Arc Mark (Arc)

Arc mark s used to draw arcs and can create visualization effects such as pie charts and ring charts. The graphic type is declared as 'arc'.

Path Mark (Path)

Path mark is used to draw arbitrary shapes of paths, creating visualization effects such as custom shapes and geographic trajectories. The graphic type is declared as 'path'.

Rule Mark (Rule)

Rule mark is used to draw straight lines and can create visualization effects such as guide lines and reference lines. The graphic type is declared as 'rule'.
