Support importing the exported JSON data
I do a lot of UML diagraming with Lucidchart and being able to export the diagram to JSON is great because it is an easy way to provide the raw data to an LLM for implementation. However, there is no way to import the same JSON data back into Lucidchart. This would be very useful because the same LLM can update the JSON with proposals or with code changes that were not included in the original UML diagram. I know the MCP server allows an LLM to update a diagram, but I found that the LLMs are much better at updating the JSON than they are at using the MCP server.
