Free visio software for linux

Kivio is a flowcharting and diagramming application for the KOffice application suite, and has an userinterface that is similar to Visio.
Kivio project is fully integrated into KOffice and can for example be embedded into KWord.
Main features:
- Scriptable stencils using Python.
- Support for Dia stencils.
- Plugin framework for adding more functionality.

Inkscape is an open source SVG editor with capabilities similar to Illustrator, CorelDraw, Visio, etc. Supported SVG features include basic shapes, paths, text, alpha blending, transforms, gradients, node editing, svg-to-png export, grouping, and more.
Inkscapes main motivation is to provide the Open Source community with a fully XML, SVG, and CSS2 compliant SVG drawing tool.
Additional planned work includes conversion of the codebase from C/Gtk to C++/Gtkmm, emphasizing a lightweight core with powerful features added through an extension mechanism, and establishment of a friendly, open, community-oriented development processes.

DataDrafter project is a new and unique program that allows you to create your own interactive graphics applications with data editing, navigation, search and reporting features built in. Use DataDrafter instead of Visio for example, to create diagrams, maps and technical drawings that are interactive and fully integrated with your data.

Your visualizations become real applications instead of just wall paper. You can even share your graphics and data as an application on the web or on your own intranet.
If you use a combination of drawings and spreadsheets to manage data, try using DataDrafter instead.

The Integrated Data/Graphics Environment ensures that both your data and graphics stay synchronized. With DataDrafter your drawings become an interactive part of your data management process. Why put all that effort into your drawings just to hang them on the wall? Put them to work for you and others while keeping them up to date with DataDrafter.

PhotoRec is a small tool to recover pictures from digital camera memory. Photorec software searches for MOV and JPEG headers, and because there is (usually) no data fragmentation, it can recover the whole file.
It can recover data from CompactFlash, Memory Stick, SecureDigital, SmartMedia, Microdrive, MMC, USB Memory Drives...
PhotoRec is safe to use, it will never attempt to write to the drive or memory support you are about to recover from. Recovered files are instead written in the directory from where you are running the PhotoRec program.
Photorec ignores the filesystem, this way it works even if the filesystem is severely damaged.
It can recover lost files at least from:
- FAT,
- NTFS,
- EXT2/EXT3 filesystem
Digital Camera
PhotoRec has been successfully tested with:
- Canon EOS300D, 10D
- HP PhotoSmart 620, 850, 935
- Nikon CoolPix 775, 5700
- Olympus C350N, C860L, Mju 400 Digital, Stylus 300
- Sony DSC-P9
- Praktica DCZ-3.4
- Casio Exilim EX-Z 750
PhotoRec searchs known file header and because there is no data fragmentation (usually), it can recover the whole file. Photorec recognises numerous file format including:

Enhancements:
- A new method for handling fragmented data is now used, making recovery more reliable and faster.
- This release can be set to search for files in FAT16/FAT32 unallocated space only, which avoids wasting time recovering files that are still accessible, making the recovery of lost files much faster and more efficient.
- New file formats have been added.

UML::State is an object oriented module which draws simple state diagrams.

SYNOPSIS

use UML::State;

my $diagram = UML::State->new(
$node_array,
$start_list,
$accept_list,
$edges
);

# You may change these defaults (doing so may even work):
$UML::State::ROW_SPACING = 75; # all numbers are in pixels
$UML::State::LEFT_MARGIN = 20;
$UML::State::WIDTH = 800;
$UML::State::HEIGHT = 800;

print $diagram->draw();

ABSTRACT

Are you tired of pointing and clicking to make simple diagrams? Do your wrists hurt thinking about making the pretty UML your boss likes so well? Consider using UML::State and UML::Sequence to make your life easier.

UML::State together with drawstate.pl allows you to easily generate state diagrams. You enter them in something like a cross between ASCII art and school room algebra. They come out looking like something from a drawing program like Visio. See drawstate.pl in the distribution for details about the input format and the samples directory for some examples of input and output.

You will probably use this class by running drawstate.pl or drawstatexml.pl which are included in the distribution. But you can use this package directly to gain control over the appearance of your pictures.

The two methods you need are new and draw (see below). If you want, you may change the dimensions by setting the package global variables as shown in the SYNOPSIS. Obviously, no error checking is done, so be careful to use reasonable values (positive numbers are good). All numbers are in pixels (sorry by Beziers in SVG seem to require pixels). I have not tried changing the numbers, so I dont have any idea if doing so makes reasonable changes to the output.

PHPflow project is a programming flowchart construction program.

PHPflow is a program that provides browser-viewable flowcharts without the need for Visio-like browser-plugins.

All flowchart symbols are drawn as PNG images, and flowcharts are built by wrapping data provided in an ini file into a customizable template using the PNG symbols.
