More generally - be aggressive with your data: probe it, sort it, graph it, sanity check it, and never take it at face value.

That's a terrible visualization. It takes way too long to work out what "the story" is.

Curious about what other libraries people use. Matplotlib? Matlab?

I've used VTK before. The learning curve is much larger and it's a huge library. But it does have a lot of inbuilt functionality like database access with filters/conversions to format the data the way you need it.

In the color science community lots of people use matlab. I find matplotlib and numpy to be a great combination.

It's really only useful when interactive - http://www.jasondavies.com/parallel-sets/ - and it still takes a while to figure out what's going on.

Jesus, is that visualization supposed to help? I stared at it for minutes and I still don't really grok it. Seems like it is trying to channel a similar method as the Napolean March: http://bryanrulli.files.wordpress.com/2011/05/tufte_napolean...

But failing completely at it.

In any case, is this a common type of visualization now? Maybe with some experience it becomes easy to grok what is happening?

The table for "Age = Child, Survived = No" is the same as the table for "Age = Adult, Survived = No". Odd, to say the least. One wonders where this interesting fact is shown in the visualization.

In engineering we use a lot of Matlab.
