Mermaid Gantt diagrams are great for displaying distributed traces in Markdown. Bryce Mecum demonstrates how Mermaid gantt diagrams can be used to render trace information, such as the traces you might get from OpenTelemetry. I tried this out in a Gist and it works really well - GitHub Flavored Markdown will turn any fenced code block tagged mermaid containing a gantt definition into a neat rendered diagram.
