Nick,

Thanks for trying this out.  I tried this again using emacs -Q with both
emacs27 and emacs28, and I still get the same result, i.e., it produces
the link but does not display it inline.  Both versions supported
display of SVG graphics files.

I did the following:

1. Start emacs with the -Q flag
2. Load the file inline.el (shown below)
3. Create a directory 'dots' in the current directory
4. Open the file inline.org (shown below)
5. Run C-c C-c on the dot src block in inline.org and confirm execution
   of the block
6. Org creates the SVG file, but does not display it.
7. If I remove the ':dir dots' header argument, the image /does/ display
   inline.

If others could try this out, I would appreciate it.
