triangulation_svg, a C code which creates an SVG image of a triangulation, which can be displayed by an web browser.
The code reads one file listing the nodes, and a second file consisting of groups of 3, 4 or 6 nodes that make up elements.
triangulation_svg prefixwhere 'prefix' is the common prefix for the node and element files, and will also be used to name the output file:

triangulation_svg is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version.
TRIANGLE_SVG, a C code which uses Scalable Vector Graphics (SVG) to plot a triangle and any number of points, to illustrate quadrature rules and sampling techniques.
TRIANGULATION, a C code which carries out various operations on order 3 ("linear") or order 6 ("quadratic") triangulations.
TRIANGULATION_NODE_TO_ELEMENT, a C code which reads files describing a set of nodes, their triangulation, and the value of one or more quantities at each node, and outputs a file that averages the quantities for each element. This operation in effect creates an "order1" finite element model of the data.
