Ploticus is script-driven, which makes it suitable for automated, unattended
uses, or for applications that will be run again and again. Ploticus might be
your choice for stylistic reasons or just because it suits the problem or
application. In general, ploticus is good at making graphs like you would see
in newspapers and news magazines, business publications, journals for medical
and social sciences, and so on.
You can also use Ploticus in combination with standard desktop tools, e.g.
generate data displays using ploticus then import SVG or PNG into PowerPoint,
Word, etc.)
Ploticus is not a function or mathematical plotting package like gnuplot, nor
would it be a good choice for applications where mathematical formulas or
scientific notations are to be rendered as an integral part of the data
display. Ploticus is also not intended as a "marketing" graphics package. Its
goal is to display data crisply without extra decoration and distracting
"dingbats" that cloud the picture. Thus there is little support for 3-D
effects, gradient backgrounds, and so on.
FreeBSD note: the binary is referred to as 'pl' in the source files, but
is installed as 'ploticus' so as to avoid conflicts with other ports.

These are the Ada bindings for math/plplot, a cross-platform software
package for creating scientific plots.
PLplot is a library of C functions that are useful for making scientific
plots from a program written in C, C++, or Fortran. The PLplot library
can be used to create standard x-y plots, semilog plots, log-log plots,
contour plots, 3D plots, mesh plots, bar charts and pie charts. Multiple
graphs (of the same or different sizes) may be placed on a single page
with multiple lines in each graph. Different line styles, widths and
colors are supported. A virtually infinite number of distinct area fill
patterns may be used. There are almost 1000 characters in the extended
character set. This includes four different fonts, the Greek alphabet and
a host of mathematical, musical, and other symbols. The fonts can be
scaled to any desired size. A variety of output devices are supported and
new devices can be easily added by writing a small number of device
dependent routines.
SVGMath is a command-line utility to convert MathML expressions
to SVG, written entirely in Python.
FFC works as a compiler for multilinear forms by generating code (C++) for
the evaluation of a multilinear form given in mathematical notation.
The FInite element Automatic Tabulator FIAT supports generation of arbitrary
order instances of the Lagrange elements on lines, triangles, and tetrahedra.
Paraphrasing the website:
Gato - the Graph Animation Toolbox - is software [toolkit] which visualizes
algorithms on graphs.
- Graphs are mathematical objects consisting of vertices, and edges
connecting pairs of vertices.
- Algorithms might find a shortest path - the fastest route - or a minimal
spanning tree or solve one of other interesting problems on graphs:
maximal-flow, weighted and non-weighted matching and min-cost flow.
- Visualisation means linking cause - the statements of an algorithm -
immediately to an effect - changes to the graph the algorithm has as its
input - by terms of blinking, changing colors and other visual effects.
The Unified Form Language (UFL) is a domain specific language for declaration
of finite element discretizations of variational forms.
Qalculate! is a multi-purpose desktop calculator. It is small and simple to
use but with much power and versatility underneath. Features include
customizable functions, units, arbitrary precision, plotting, and
a user-friendly interface.
