Open Source Perl Data Visualization Software

xoscope is a digital oscilloscope using input from a sound card or EsounD and/or a ProbeScope/osziFOX and will soon support Bitscope hardware. Includes 8 signal displays, variable time scale, math, memory, measurements, and file save/load.

The PDL module gives standard perl the ability to COMPACTLY store and SPEEDILY manipulate the large N-dimensional data sets that are the bread and butter of scientific computing.

Flame graphs are a visualization of profiled software, allowing the most frequent code-paths to be identified quickly and accurately. They can be generated using my open source programs, which create interactive SVGs. See the Updates section for other implementations. Recently I've been helping with d3-flame-graph. The x-axis shows the stack profile population, sorted alphabetically (it is not the passage of time), and the y-axis shows stack depth, counting from zero at the bottom. Each rectangle represents a stack frame. The wider a frame is is, the more often it was present in the stacks. The top edge shows what is on-CPU, and beneath it is its ancestry. The colors are usually not significant, picked randomly to differentiate frames. Flame charts were first added by Google Chrome's WebKit Web Inspector (bug). While inspired by flame graphs, flame charts put the passage of time on the x-axis instead of the alphabet.

AquaTerm is a Mac OS X grahics renderer. It allows command line applications written in ObjC, C, FORTRAN, Lisp, Perl or Python to display vector graphics, text and images using a simple API. Adapters for gnuplot, PGPLOT, and PLplot exists as well.

NOTE: Code commits are FROZEN on SourceForge: New code is now at <http://github.com/Xastir/Xastir>. Real-time tracking & messaging of stations via radio/internet APRS data streams, w/125 map formats supported. Linux/FreeBSD/Solaris/MacOSX/Windows in any of 7 languages. Can also be used for mobile mapping w/GPS. MAILING LISTS ARE AT: PROJECT->WEB SITE.

Create colorful WiFi signal strength maps from NetStumbler GPS and signal data. Compatible with Google Earth. As far as we know, this is the only dedicated wifi mapper / map generation software currently available under GPL.

VisIt is an interactive parallel visualization and graphical analysis tool for viewing scientific data.

A generic geospatial analysis and viewing capability using Perl scripts that provides the foundation and structure for readily creating KML data files from disparate data sources. KML files can be read and viewed by Google Earth and other tools.

Software for the Conrad/Voltcraft Charge Manager 2020 (CM2020) battery charger

Krona allows hierarchical data to be explored with zoomable HTML5 pie charts. Krona charts can be created using an Excel template or Krona Tools, which includes support for several bioinformatics tools and raw data formats.

Plotmeister is a data exploration tool. It parses your ASCII data and generates a simple (text-based) table format. You can modify this table and eventually create nice looking figures.

Vcd2txt is an utility to parse value change dump (VCD) files and convert them to an easily readable (plain-text) table of signals. In contrast to GTKwave, simulation of hardware circuits can be performed fully on the command line.

Simulates and visualizes swarming algorithms with limited communication. Also provides an interface to animate particle motion by playback (with pause, fastforward, and rewind) of path information from files. Can output EPS figures and avi frames.

EdgeExpressDB (eeDB) is a federated data abstraction system designed for integrating, interpreting, and visualizing very large biology datasets. It is designed for scaling beyond Petabytes and 10^13 objects. http://fantom.gsc.riken.jp/4/edgeexpress

Evoker is a graphical tool for plotting genotype intensity data in order to assess quality of genotype calls. It implements a compact, binary format which allows rapid access to data, even with hundreds of thousands of observations. PLEASE NOTE: This source repository is no longer active. See the github link above for the latest version.

GPLIGC is a program for analysis and 3D visualization of GPS tracklogs (in igc format) as recorded by flight data recorders used by glider pilots.

Data mines the voting record and other actions of Members of the UK Parliament. Extracts information from the parliament website and stores it in a database. Provides tools to analyse the information, producing statistics and tables about the MPs.

CViT - Chromosome Viewing Tool. A collection of Perl scripts that enable quick visualizations of features on linkage groups, psuedochromosomes or cytogenetic maps. Intended for whole-genome views of data but can be used to create images of single chromosomes/linkage groups, contigs, or BACs, or even proteins -- any feature that has a location on a backbone. Handles most standard genetic/genomic coordinate systems. Reads GFF3 data and produces a PNG or SVG image.

A Perl object-oriented library for plotting graphs with Gnuplot.

This package aims to enable complex ideogram drawing in genetic applications for different species.

Corbata is a set of statistical tools that can be used to analyze the core microbiome across a set of samples.

Cscape is an application for visualizing and navigating through data from a Reverse Phase Protein Microarray (RPMA). Cscape uses the Google Maps API to map the RPMA data on top of an image of a cancer cell and its associated pathways.

Graph handling and layout software developed for helping scientific research. The interface uses Perl, the algorithms are in C++. Creates and shows 3D and 2D graph layouts (several algorithms). Has a scripting interface for graph handling.

IDEA (Interactive Display for Evolutionary Analyses) augments PAML with a graphical interface, phylogeny reconstruction using PhyML or PHYLIP, convenient and efficient parallel processing and visualizations.

ActiveGEM contains a set of perl/Tk graphical interfaces for the GEMPAK meteorological diagnostics and plotting package. These research-oriented interfaces provide easy access to low-level GEMPAK functions and allow for the maximum possible flexibility.
