Here are some cool things I've done recently with graphviz:<p>1. Draw "sketch" style graphs using <a href="https://sketchviz.com/new" rel="nofollow">https://sketchviz.com/new</a><p>2. Draw graphs of memory usage in golang programs (using pprof): <a href="https://graphviz.org/Gallery/directed/pprof.html" rel="nofollow">https://graphviz.org/Gallery/directed/pprof.html</a><p>3. Embed graphviz into Sphinx docs (shameless self-promotion:  <a href="https://docs.robusta.dev/master/catalog/triggers/index.html#trigger-hierarchy" rel="nofollow">https://docs.robusta.dev/master/catalog/triggers/index.html#...</a>)
