This project extends a previous work on node link tree visualisation and interaction by providing visual clues on hidden structures. We adopt DOITree from Prefuse package (https://github.com/prefuse/Prefuse), a multi-focal tree layout algorithm, for exploring large hierarchical structures.

TreeDraw is a object-oriented Java class framework to aid in visualizing tree data strucures. It consists of a few abstract classes. If you derive your tree, nodes, and edges from these abstract classes, you can easily visualize your data structure.

Efficiently create compact, highly customizable tree layouts - Based on Walker's algorithm with enhancements suggested by Buchheim, Jünger, and Leipert the software builds tree layouts in linear time. I.e. even trees with many nodes are built fast. Downloads are available at https://sourceforge.net/projects/treelayout/files/. For detailed documentation look at the TreeLayout web site http://treelayout.sourceforge.net/. Development for TreeLayout has moved to https://github.com/abego/treelayout/.

A treemap visualization java library, to implement Shneiderman's treemap easily (http://www.cs.umd.edu/hcil/treemaps/). Shows efficiently tree data as a rectangle colored map. Usefull to monitor thousand of files in a little window.

A modular framework build upon OSGi supporting scientific data interrogation, manipulation and visualisation.

By using a neural net from neuroph.org with the programmlanguage Java, you can change the net by this software. Easy watch it on the screen and move the values up or down. More or less value at the output neurons. Saving, Loading from different .nnet`s. Adding comments. Changing the visible output neuron Setting wished input neurons to get visible. A small fast and easy weight version and a continuing version, which should get involved in the neuroph project.

Showing or hiding toolbar and floating button when scrolling. Scrollbars and colorful styles of swipe to refresh. Sticky header like instagram. Support different layout in adapter. Loading adapter with animation. Expandable view in recyclerview.

The Universal Java Matrix Package (UJMP) is an open source Java library which provides sparse and dense matrix classes, as well as a large number of calculations for linear algebra such as matrix multiplication or matrix inverse. Operations such as mean, correlation, standard deviation, replacement of missing values or the calculation of mutual information are supported, too. The Universal Java Matrix Package provides various visualization methods, import and export filters for a large number of file formats, and even the possibility to link to JDBC databases. Multi-dimensional matrices as well as generic matrices with a specified object type are supported and very large matrices can be handled even when they do not fit into memory.

This project moved to GitHub in 2021 and is available at: https://cbrinkrolf.github.io/VANESA/ This tool is a platform-independent software to create individual pathways and to examine biological networks of distributed, heterogeneous data sources, e.g. KEGG, BRENDA. VANESA also offers Petri net modeling of extended hybrid Petri nets which can be also simulated using the OpenModelica framework.

It provides a graphical animated representation of a network simulation run (e.g. for ns-2). Further, common metrics are calculated and displayed. The tool is written in Java and supplies 2 frontends (applet and stand-alone application).

VERDI is a flexible, efficient, and modular Java-based visualization software tool that is used to visualize multivariate four dimensional gridded environmental datasets such as those output by air quality models.

VLSI Layout 3d is a 3d visualization software for VLSI designs created in LASI. This project is gearing up to go open-source!

VMS Draw provides general utilities (e.g. normalization, conversion, and other manipulations of several spectra at the same time) and a flexible graphical user interface (GUI) for an easy use by non-specialists which allows a seamless flow of information between experimentally and theoretically oriented researchers. Finally, it permits effective interactions with other electronic structure codes [e.g., nuclear magnetic resonance (NMR), microwave] even if Gaussian 16 offers the widest set of methods for computational spectroscopy.
