Basic Visualization Terminology

Visualization
- the graphical (as opposed to textual or verbal) communication of information (e.g. data, documents, structure)

Interaction
- a fundamental component to visualization which permits user-specified modifications to the visualization parameters

Data model
- representation of data, may include structure, attributes, relationships, behavior, and semantics as well as repository for data values themselves

Graphical attributes
- user-controllable aspects of the image generation process, including position, size, color, shape, orientation, speed, texture, and transparency of graphical entities

Mapping
- associating data values and attributes to graphical entities and attributes

Rendering
- creating and displaying an image

Field
- a grid of data points, may be uniform/nonuniform

Scalar
- a single numeric data value

Vector
- a 1-D list of values associated with a single datum

Tensor
- a 2-D array of values associated with a single datum

Isosurface
- contours or boundaries in a field with a common value, usually dependent on interpolating between values in the field

Glyph
- shape or image generated by mapping data components to graphical attributes, also called an icon
