While Draw.io's integration with Mermaid and the availability of plug-ins for VSCode and other IDEs are great, they primarily support programmatic editing of diagrams. What sets Mermaid Chart apart is its bi-directional editing capability. You can edit the code to update the diagram and make changes directly to the diagram, which will automatically reflect in the code.

Currently, this two-way editing functionality is available for class diagrams and flowcharts, but we're excited to expand it to other popular diagram types in the future. Stay tuned!
