Abstract

The abstract is the 300 character elevator pitch for this talk

Data visualization is hard. Let's say a designer hands you a single example, with simple data. How do you build something that will handle the complexity of real-world data? Find the rules and constraints

/*

It is not the critic who counts; not the man who points out how the
strong man stumbles, or where the doer of deeds could have done them
better. The credit belongs to the man who is actually in the arena,
whose face is marred by dust and sweat and blood; who strives valiantly;
who errs, who comes short again and again, because there is no effort
without error and shortcoming; but who does actually strive to do the
deeds; who knows great enthusiasms, the great devotions; who spends
himself in a worthy cause; who at the best knows in the end the triumph
