Visualization Pipeline

The visualization pipeline describes the (step-wise) process of creating visual representations of data.

1. Data Analysis: data are prepared for visualization (e.g., by applying a smoothing filter, interpolating missing values, or correcting erroneous measurements) -- usually computer-centered, little or no user interaction.
2. Filtering: selection of data portions to be visualized -- usually user-centered.
3. Mapping: focus data are mapped to geometric primitives (e.g., points, lines) and their attributes (e.g., color, position, size); most critical step for achieving Expressiveness and Effectiveness.
4. Rendering: geometric data are transformed to image data.
