Visualization of pathfinding algorithms

Cool!

Visualization of WiFi strength using the Helmholtz equation

This kind of stuff melts my brain.

Mapping the ArXiv

And speaking of analysis of large scientific/mathematical structure, here's a map of the ArXiv using some kind of similarity metric that I have no idea about.

Up and Down the Ladder of Abstraction

Fantastic article on visualization as a tool for thinking, and simultaneously kind of a call to action for programming tool makers.

Bret Victor and data visualization

Wow. I'm not normally one to take the time to watch a video, but this one was worth it.  Victor is essentially building drawings at the semantic level - his tool even expresses the semantics of the steps in words!  Fantastic vision.

I can't even watch it straight through. The idea cascade is deafening.

Vega: DDD Visualization Grammar

Now this is a neat idea.

Visualizing.org

I think maybe I linked visualising.org once before, but the affairs of Zeus are kinda neat.

Learn visualization!

A recommendation to people new to scientific programming: learn visualization tools, especially fast ones.  The post has some nice specific recommendations, including R.

This is getting to be kind of a common thread lately in what I'm reading.  Ooh, Z has come up with something nice here: MetaSee for metagenomic visualization (open source).

The Goal is to be Like a Bad Hacker Movie

This post by James Hague is what took me to his site this week.  The idea is quick turnaround, like in hacker movies.  And he's right.  Instant-on programming would be a fantastic thing to have at your fingertips, and sometimes our current tools nearly allow us to achieve it.

But data analysis with quick plots, yeah, that too.

Visualization in Perl (and not in Perl)

There was a post to the Quantified Onion group this week about visualization in Perl.  Here are some useful links that arose from that discussion.

• Gephi open-source graph visualization tool
• CPAN mapping

Visualizing log entries

Here's an utterly fascinating code article: parsing the SSH logs for cracking attempts and displaying them on an animated world map based on IP geolocation. Wow!

Kill Math

I can't remember whether I've blogged this before, but this kind of visualization stuff always turns me on. The Kill Math project is devoted to finding ways to model math interactively and intuitively, to solve problems without symbolic algebra. It's pretty neat stuff.

Weave: Web-based Analysis and Visualization Environment

I haven't looked too closely at this, but it looks neat.

Visualizing sorting algorithms with Python and Cairo

Here's a nice article about visualizing sorting algorithms [github] - but I like the fact that the graphics generated are really nice-looking. They use the Cairo graphics engine, which I clearly need to examine more closely.

More recently, the same guy did some visualizations of malware.

Twitter influence graph on SOPA

Nice visualization. I'm a sucker for this stuff.

2011 Visualization Roundup

What it says on the tin.
