I used #matterjs to do a bit of data visualization using physical metaphors and I loved it. We should all do more #datavisualization with physics engines, especially for systems like this.
Also, if you want to learn about watermarks, give it a try.

Looks like I'm going to get to revisit design principles for animated #dataviz. Any good resources out there that folks rely on for animation in data visualization?
