Spaghetti Parenthesis Visualizer is an in-browser (meaning that it doesn't send your code to a server) tool that takes deeply nested conditionals in languages that follow in C's footsteps, including Python, Perl, PHP, and Java, SQL queries, or some Lisp code, and provides two visual presentations that clearly and cleanly display how deep each part of the code is in the layers of nesting.
TNV (The Network Visualizer or Time-based Network Visualizer) depicts network traffic by visualizing packets and links between local and remote hosts. It is intended for network traffic analysis to facilitate learning what constitutes 'normal' activity on a network, investigating packet details and security events, or for network troubleshooting. It can open saved libpcap (from tcpdump, windump, ethereal, etc.) formatted files or capture live packets on the wire, and export data in libpcap format or save the data to a MySQL database to enable the examination of trends over time.
h5utils is a set of utilities for visualization and conversion of scientific data in the free, portable HDF5 format. Besides providing a simple tool for batch visualization as PNG images, h5utils also includes programs to convert HDF5 datasets into the formats required by other free visualization software (e.g., plain text, Vis5d, and VTK).
