Vz_plot
Quick cartesian plots of datasets.
An Evidence
observation is represented by a graphical mark whose properties like position, color, opacity, etc. is defined by the values of its variables.
Visual units. To make it easier to think about the visualization in terms of human factors we assume the coordinate system of the visualization is in millimiters. But this being vector graphics the final rendering size depends on the size of the renderable.
References. The good ideas are from ggplot2, Vega-Lite, and observable plot.
