Should the next version of HTML, the Web standard that embodies how pages are laid out and constructed, include explicit specifications for inline, 2-D dynamic graphics? There’s valid arguments on both sides. One side believes that the ability to plot charts and animations would have been part of the original HTML standard anyway, had the technology existed on the back end in the beginning; giving HTML 2-D graphics now, they say, plugs a hole left open for too long. Another believes the HTML5 standard should simply specify an API for plug-ins.
