Cannot get working links in graphviz

[wsw70]

question initially asked at stackoverflow but it looks like this is rather a bug

I use graphviz in my Sphinx documentation and would like to reuse links automatically generated by the RestructuredText code.

The output I get from

Hello
-----
Test of a graph

.. graphviz::

    digraph process {
           a [label="first", href="http://google.com"];
           b [label="second", href="#World"];
           a -> b;
        }

World
-----
Something else.

is correct, but despite the fact that the generated image is an SVG, firstand second are not clickable:

If I right click the embedded image and open it in a new tab, it has active links I can click on. It looks like if embedding the image prevented the links from being active.

The elements of my conf.py relevant to graphviz:

extensions = [
    'sphinx.ext.todo', 'sphinx.ext.graphviz'
]
graphviz_output_format = 'svg'

Is there something specific to set up in Sphinx to have this behaviour for embedded graphs?

MEMO: related with #2014 and #2176

[tk0miya]

For now, #2176 is merged into stable branch.
It enables to click the links in SVG images.
Please check it.

Thanks,

Hello @tk0miya and @wsw70,
Found this issue while looking for a way to make the PNG images generated from the graphviz extension clickable.
Is there a way to open the PNG in another window with a click?

Hello @Ellon , I recommend you to ask in the https://groups.google.com/g/sphinx-users mailing list, Stack Overflow, or open a new feature request if you are certain that what you're asking cannot be done at the moment. Commenting on a 6 year old issue that's unrelated to your question makes it less visible and you're less likely to get help.
