I have a python program that uses graphviz to generate an svg image that it prints out. When I run that in a shell buffer I see a textual representation of the svg image. I'd like to see instead the generated image. How do I take that text in emacs and get something that shows me the image?

Pipe the output of the python program into the standard input of an image display program that can read from stdin (e.g. `display` which is part of ImageMagick, can read stdin: `cat foo.svg | display -`) – NickD Aug 20 '23 at 18:46

Ok, thanks that is helpful. Now I will go look for imageMagick and how to install it.... – Christopher Clark Aug 20 '23 at 19:00

Check whatever image display program you have available first: `display` is just one example that should work. – NickD Aug 20 '23 at 20:05

I am not sure where and how you are running Emacs, but I think graphical Emacs can show the svg image itself also in most cases. Then the following answer is an alternative to the answer by @NickD in the comments.
I am not sure if you need to run the command in a shell buffer per se, but otherwise you could also use the following command (via M-x or create a keybinding):
(defun display-output-as-image (command)
(interactive
(list
(read-shell-command (if shell-command-prompt-show-cwd
(format-message "Shell command in `%s': "
(abbreviate-file-name
default-directory))
"Shell command: ")
nil nil
(let ((filename
(cond
(buffer-file-name)
((eq major-mode 'dired-mode)
(dired-get-filename nil t)))))
(and filename (file-relative-name filename))))))
(shell-command command
(pop-to-buffer "output.svg"))
(image-mode))
Then, after calling this command, you can simply type in the command and the image will show in an Emacs buffer.
