PROV Graph Layout Conventions

It is recommended to follow the following conventions to display PROV graphs.

Luc, Mar 28

Entities, activities and agents are represented as nodes, with oval, rectangular, and octagonal shapes, respectively. Usage, Generation, Derivation, and Activity Association are represented as directed edges.

Entities are laid out according to the ordering of their generation. We endeavor to show time progressing from left to right. This means that edges for Usage, Generation, Derivation, Association typically point leftwards.

Alternatively, time going downward if it's more convenient.

• Entities are yellow ovals
  • Fill:
    • Saturated: (255, 252, 135) or #FFFC87
    • Desaturated: (255, 253, 229)
  • Stroke: medium gray (128, 128, 128)

• Activities are blue rectangles
  • Fill:
    • Saturated: (159, 177, 252) or #9FB1FC
    • Desaturated: (216, 217, 254)
  • Stroke: blue (0, 0, 255)

• Agents are orange "pentagon houses" (alternatively, upward isosceles triangles)
  • Fill:
    • Super-Saturated: (253, 178, 102)
    • Saturated: (254, 211, 127) or #FED37F
    • Desaturated: (253, 238, 205)
  • Stroke: black (0, 0, 0)
