Create bar charts in SVG instead of HTML tables

[mthuurne]

Currently the bar charts on the ExtractedData page are HTML tables. This was picked as a cross-browser solution at the time this feature was implemented (2006). However, now we can use SVG instead, which is both more elegant and more flexible.

Something to look at when converting to SVG is whether we can use links in SVG instead of JavaScript to make the bars clickable. The problem with JavaScript links is that APE cannot check them.
