Application to help build diagrams

I know the paper and a pen answer, but I truly need a PC solution.

I made the example below by Word, so please recommend others more suitable and convenient.

By suitable and convenient, I mean I can edit more easily - for example, in Word, if I add something, I have to scale and adjust the whole. In other words, I want something a little bit like SmartArt for focusing on programming illustrations.

Thanks.

A popular choice for this is Dia. Not only is it free and open-source, it's cross-platform, supports UML diagrams (click me for some examples), and has a variety of additional libraries and shapes that you can find for free. You can also export your drawings in a variety of formats - even lossless and vector.

You can get Dia here for Windows, or here for Linux

What you need is a UML tool. Some are incorporated into your IDEs .
Check this Wikipedia entry for a list of available tools.

You can try the yEd, which can also be started from a browser:

yEd is a powerful diagram editor that can be used to quickly and effectively generate high-quality drawings of diagrams.

Create your diagrams manually or import your external data for analysis and auto-magically arrange even large data sets by just pressing a button.

yEd is freely available and runs on all major platforms: Windows, Unix/Linux, and Mac OS.

You might also take a look at Visual Paradigm (Windows only). There is a free community edition available.

My personal favorites:

  • Altova UModel - Can be complex, but it's not necessary to use every function. (Commercial)

  • Violet - Simple, but sufficient for most technical software diagrams using UML like elements. Can run via Java Webstart so no installation required. (Free)

(Edit: Modified Violet link to use official URL which redirects to newer site and version. Also noted Violet's support for webstart).

I use graphviz and dot to create diagrams. With this you can easily make diagrams from text to almost any output you like: PNG, PDF, and more (http://www.graphviz.org/doc/info/output.html).

To install: sudo apt-get install graphviz

Example hello.dot:

digraph G {
        fontname = "Bitstream Vera Sans"
        fontsize = 8

        node [
                fontname = "Bitstream Vera Sans"
                fontsize = 8
                shape = "record"
        ]

        edge [
                fontname = "Bitstream Vera Sans"
                fontsize = 8
        ]

        Animal [
                label = "{Animal|+ name : string\l+ age : int\l|+ die() : void\l}"
        ]

        Dog [
                label = "{Dog||+ bark() : void\l}"
        ]

        Cat [
                label = "{Cat||+ meow() : void\l}"
        ]

        edge [
                arrowhead = "empty"
        ]

        Dog -> Animal
        Cat -> Animal
}

$dot -T png -o Animal.png hello.dot

The result is as:
