Describe the issue

I’m using GraphRAG version 3.0.6. After running graphrag index, a set of .parquet files is generated in the output directory. These files work correctly with graphrag query "test...", so the index itself appears to be valid.

However, when I upload these .parquet files to the GraphRAG Visualizer at https://noworneverev.github.io/graphrag-visualizer/#/upload, both Nodes and Relationships are reported as 0, and no graph is rendered.

I’d like to ask whether this is likely due to a change in the .parquet schema/output format in GraphRAG v3.0.6, or if there might be an issue on the visualizer side. In short: are the .parquet files produced by v3.0.6 incompatible with the current visualizer?

Thanks in advance for any guidance.
