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 […]
