Open Source C++ Data Visualization Software

FractalNow provides users with tools to generate pictures of various types of fractals quickly and easily. It is made of both a command line tool, FractalNow, and a graphical tool, QFractalNow. The graphical tool, based on Qt library, allows users to explore fractals intuitively and generate pictures. Both tools are entirely multi-threaded and implement advanced algorithms and heuristics that make computation very fast compared to most existing free fractal generators.

Hypercube is a tool for visualizing DOT (graphviz), GML, GraphML, GXL and simple text-based graph representations as SVG and EPS images. Hypercube comes with a Qt based GUI application and a Qt-independent command-line tool. It uses a simulated annealing algorithm to lay out the graph, that can be easily parameterized to achieve the desired look. The main development goals are portability and easy usage rather than high performance and complexity.

A command line tool for generating timing diagrams from ASCII input files. The input files use a structured language to represent signal state transitions and interdependencies. Raster image output support is provided by ImageMagick.

Dynagraph is a cross-platform library and command-line tool for dynamically drawing graphs (networks, flowcharts, family trees, etc.) in reponse to continual modifications. Included are DynaDAG for directed graphs and FDP force-directed placement.

A command-line tool for applying the continuous wavelet transform with respect to predefined wavelets to sampled data.

pepper is a command-line tool for retrieving statistics and generating reports from source code repositories. It ships with several graphical and textual reports, and is easily extendable using the Lua scripting language.
