I disagree, as even if you did use Javascript the service is still far more accessible to a novice developer than something like the d3.js library (which I love, but has a rather steep learning curve).

Additionally, you would be surprised at how much could be accomplished in that department with just CSS.

That's a limitation of d3.js, not JavaScript. gRaphaël is pretty easy to use: http://g.raphaeljs.com/
