SVG links appear but don't connect

I've just inserted an SVG, and written links to have several areas connect to other sites. It seems to work okay.

But now I need to insert a second SVG on the same page, and have it work the same way. But it won't cooperate.

As it was a long column to be worked on, I tried to set it in a separate page and import it to my working page:

<figure id="myMap3"> <img src="images/trngl&list_2019_right-105.svg" alt=""/> </figure>

But for some reason, the links I've set up on that page don't work. They appear in the proper location on the page, but they don't link to anything:

<a xlink:href="http://www.virtuevision.org" target="_blank" >
<title>www.virtuevision.org</title>
<rect x="18" y="31" width="450" height="22"></rect>
</a>
<a target="_blank" xlink:href="https://www.juliecohnfineart.com">
<title>www.juliecohnfineart.com</title>
<rect x="18" y="54" width="450" height="27"></rect>
</a>

Any ideas how to get this working?

Thank you for any help you may give!
