how to create algorithm graphs

[kalos]

hello

is there an easy way to create algorithm graphs like this?



thanks

I found Dia to be pretty nice for such tasks. Inkscape also works well but is overkill in this case, I would think.

you will probably have better luck searching for a program if you use the term "flowchart".

Ummm, the suggestions were pretty good wrt. the first image you posted - instead of editing your first post and upload a completely different kind of image, you should've added that image to a new post.

[mouser]

yeah the new image is not a flowchart but a graph of data -- completely different tool needed for that.

oh i see
they resemble so much

curious now to see what the first image was lol

The current one is made by information is beautiful (http://www.informationisbeautiful.net/)
He may use other software along the way but the end product is presumably made by a vector graphics programme - I wouldnt be suprised if all that's used before that is a calculator (to scale the circles according to popularity). You're looking at top graphics there - that costs lots of time and talent, or lots of money.

You could always ask him directly what software he uses http://www.informationisbeautiful.net/about/

I'm not trying to say you couldnt do this - I'm saying you could do this - but it will take time and creativity (or you could just copy other peoples ideas I guess)

From memory  TeeChart Office can produce bubble charts similar to the one shown. It's free so could be worth a look.

teechart office isnt really meant to be a serious graphing program -- it's a demo for a (pretty powerful) developer library for adding graphing to applications you build.

One *very* easy way to make something like that is with Microsoft Publisher. My licensed copy is 2003 and with that you select "Design Gallery", "Attention Getters", "Dot Attention Getter". The location on the page, color, size and text can all be easily changed. Hope that helps. Cheers

Well, both were computer images consisting of pixels, but beyond that?

There's a new interactive version of this one (I know, it's veering off-topic, but it's still worth a look :p)

You could make something similar using word cloud software.

Here's one service for doing that:
http://www.wordle.net/

Going here gives you most control:

You make a list of phrases and then use numbers to make relative sizes.  But there doesn't seem any way with this service to enclose the phrase in a shape (like a rectangle or circle).

Try
Wordaizer: from text to word cloud with a twist
This is Freeware.
See the examples at the bottom of the url.

World clouds have become very popular. Thanks to the Wordle javascript (www.wordle.net) anyone can make a beautiful picture with words. There are however some drawbacks, such as the Wordle picture can not be saved (directly) and because of copyright modifications or alterations of the Wordle application is out of the question.
Word clouds are playful and it is very attractive way to show text. Here we offer yet another application to the list of our creativity tools: Wordaizer. This new application offer the possibility to tune, shape, create, print and save any word cloud that you can think of.

Do you want to control the shape of the word cloud?

Wordaizer is a brand new application from APP Helmond to create word clouds like Wordle does, but allows total freedom to tune almost every relevant aspect of the desired word cloud. The application is capable of making word clouds, but adds a very strong new features: masks to make your own word cloud shape. The shape of the mask becomes the blueprint of the shape of your word cloud.

Do you want to save, print or make very large word clouds?

The result from Wordaizer is a (bitmap) picture: it can be saved on harddisk, and printed. The paper size is (of course) adjustable, allowing the user to save up to A1 format (150 dpi print). You can print from within the application, or store the result on harddisk, do some post processing (if needed), print it or resize and send it to a friend by email. You have full control over the end result.

Do you want to keep that favourite setting that produced a wonderful word cloud?

With Wordaizer you can save the full settings into a so-called project file. This is a small file that stores all the relevant settings that you used in your favourite word cloud. Simply load that file and continue to make another great word cloud. We have already provided some nice project files with the installation, and you can start right away.

I guess tools like prefuse or some flash data visualization software is used for this. Prefuse get you similar looks, and so with flash.
