It's an htmlwidget for R. Create mermaid graphs. Use the shiny app to create graph specifications interactively.
Graphviz has quite the legacy for creating quality graphs. Now it's in DiagrammeR. Create graph specifications in the DOT language and take advantage of mixing R into it.
Change the way your diagram is rendered by taking advantage of all of these Graphviz engines: dot, neato, twopi, and circo.
Using mermaid, make Gantt charts. Define chunks of GraphvizDOT code using R data frames and new convenience functions.
A large selection of new functions for creating graph diagrams is now available. No need to interact directly with DOT code, just build diagrams in an R-like way.
Many more new functions were introduced to make it easier to inspect, analyze, and modify graphs.
Includes support for visNetwork graph rendering. More graph functions added, and, all functions optimized for piping.
Mermaid CLI Mermaid Diagrams on Hugo More. I have Grafana to thank for introducing me to Mermaid diagrams - one day at work a new Diagram widget appeared and naturally I had to explore further. What I found amazed me. If you are a fan of diagramming, markdown, and CLI tools - and have not heard of Mermaid, you are in for a treat! This is done by defining mermaid.sequenceConfig or by the CLI to use a json file with the configuration. How to use the CLI is described in the mermaidCLI page. Mermaid.sequenceConfig can be set to a JSON string with config parameters or the corresponding object.

you are also supplying width and height configuration for generated png file. sequence.mmd file contains below markdown text syntax
Mermaid Live Editor tool
This is online Editor tool to edit/preview/download mermaid flowcharts and diagrams. This will be very useful for coding mermaid definition file and test and preview the diagram flows. This will help developers to save time and debug if any issues. This has also various options like generate the link for the generated diagram and share it with others, Others can also edit the code and see the diagram. You can also download generated flow as SVG file.
