The issue occurs when exporting to HTML
When a jfree chart has a hyperlink on the series and the Render Type is 'default', 'draw', or 'image', hyperlinks work as expected.
When we change the Render Type to SVG, the hyperlinks appear in the 'area' tag, but the image appears to be missing the 'usemap' attribute.
When previewing an SVG rendered chart in JSS using HTML, the hyperlinks are not working.
When previewing the same SVG rendered chart in the JSS java viewer, the hyperlinks are functional.
