Use dot to generate graphviz static images.
- dot / graphviz
{% graphviz "Caption of the graphviz" %}
digraph {
A -> B;
}
{% endgraphviz %}
The content of the tag will be hashed and that will form the basis of the filename. If the content hasn't changed, the graph won't be re-generated.
Due to the way file watching works, the image generation will cause a new render to start happening. There is a check to prevent it from entering into an infinite regress, but "Reloading browser" will appear twice.
The html for the created image is in the template img.ejs, and it matches pandoc's default output. Allowing a user to override that in either _config.yml or the tag itself would be very nice.
