[R] insert hyperlink into svg graphic

[Boris Steipe]

This was actually the first thing that ChatGPT debugged for me.

The issue was that I was able to click on the link when I displayed the raw SVG in the browser (you can use that to test whether the syntax is even correct), but not when the svg displays inside a html page with the <img ...> tag.

ChatGPT correctly identified the issue and suggested a solution using <object ...> tags instead.

Here's how that would work:

<object data="temps.svg" type="image/svg+xml" alt="Image description TK">
<p>Your browser does not support the <object> tag.</p>
</object>

(Most browsers support the object tag: see https://caniuse.com/mdn-html_elements_object )


Cheers,
Boris
