Insert clickable SVG image into Sphinx documentation

One simple solution would be to add a link to the svg file in this .. image:: myfile.svg command:

.. image:: myfile.svg
   :target: _images/myfile.svg

Take care of checking the relative directory where the images are copied when the html files are generated. By default, it should be _images/.

This way, you can click the SVG file, to see it in a plain page, and then click on it as usual (not a perfect solution but still..).

Sphinx generates <img> tags for images, which makes sense in most cases. However, to have the links inside the svg be clickable, you should use an <object> tag, i.e.:

.. raw:: html

    <object data="myfile.svg" type="image/svg+xml"></object>

(Regarding the GitHub issue you linked to, I don't think there's a lot that Sphinx can do here—it's really quite complicated—short of introducing a new option to the .. image directive that lets the user specify whether to render as an img or object tag.)

I am probably misunderstanding the OP's requirements, but why not just include the SVG into the sphinx documentation as html? This appears to work for me:

.. raw:: html
    :file: images/image.svg
