D3.js Data-Driven-Documents Revisited
D3.js Website and
I will revisit some of the old visualizations I createdand also try to convert some newer ideas into visualizations. Now tinkering and playing became much easier, I recommend JSFiddle if you want to avoid local web server setup, though JSFiddle does not support version 4.0 yet (at the time of writing this).
You also can run your visualization with the good old GitHub Gist and the bl.ocks site or the browser plugins .
I am working with D3 again after experimenting with visualization tools like Tableau andrealizing quickly that outstanding visualizations only can be created with the power of D3, though you have to work with sourcecode and understand whats going on under the hood of a modern web browser. Please dont forget D3 is released under the BSD license !
