The D3.js library uses pre-built functions to select elements, create SVG objects, style them, or add transitions, dynamic effects, or tooltips. These objects can also be styled using CSS. Large datasets can be bound to SVG objects using D3.js functions to generate text/graphic charts and diagrams.

CSS does not just apply to visual styling: when spoken out loud by a voice browser, CSS styling can affect speech-rate, stress, richness and even position within a stereophonic image. For these reasons, and in support of a more semantic web, attributes attached to elements within HTML should describe their semantic purpose, rather than merely ...
