Why use rfig?
- Allows you to specify the layout of your slides
in a declarative and modular way using relative spacing.
Powerpoint and other GUI-based programs rely
more on absolute positioning, which can be cumbersome.
- Makes it easy to customize the appearance (e.g., spacing, color, size)
of a type of object on many slides at once by turning one knob.
- Allows you to create many figures which
are parameterized by some value that varies throughout the slide presentation.
For example, one can define a histogram figure parameterized by a probability
distribution and use it over and over again by invoking one function call.
- Seamlessly integrates text and equations via LaTeX
to avoid the cut-and-paste look.
- Includes a library for drawing bar graphs, line graphs, and trees.
