Visual Encoding

The visual encoding is the way in which data is mapped into visual structures, upon which we build the images on a screen. It is defined in term of: Spatial substrate Graphical marks Graphical properties of the marks Spatial substrate The spatial substrate define a position of the space where we collocate graphical marks. The space is defined in term of axes. Card et al. (1999) define four elementary types of exes: Unstructured axis (no […]

Some ideas from an article proposed by Gabriele Peters at the IV07 conference in zurich: Images play an important role in visualization, and there is a need to generate also im- ages which appear aesthetically to the user. Starting with the modularities of the human visual system, six Aesthetic primitives of vision have been derived. They are: Color: use a few strong colors only; often complementary contrasts are effective; exploit the dynamic range Form: forms should be […]
