Model Graph for DTDL V3

Hello Narendra Lalwani,

It looks like you're curious about the support for model graph visualization for DTDL version 3 in Azure Digital Twins Explorer. Currently, Azure Digital Twins Explorer offers full support for DTDL v2 models. While DTDL v3 models can be imported using the Azure CLI or REST APIs, they are not yet supported in the Model Graph panel of the Explorer. This means that DTDL v3 models will not appear visually in the graph view, nor can they be imported directly through the Explorer interface.

Microsoft has not announced a confirmed timeline or release date for full DTDL v3 model graph support in the Explorer. We recommend monitoring the following resources for updates:

• Azure Digital Twins documentation
• https://azure.microsoft.com/en-us/updates/

In the meantime, if you are working with DTDL v3 and require visualization, you may consider the following alternatives:

• Programmatic visualization: Use libraries such as D3.js or Mermaid to build custom graph views from your DTDL v3 JSON definitions.
• Open-source tools: Explore Microsoft’s opendigitaltwins-tools GitHub repository for utilities that assist with model validation and transformation.

Hope this helps!
Thank you!

Hello @Narendra Lalwani ,

welcome to this moderated Azure community forum.

As mentioned in the comments, the ADT environment does not support visualizing DTDL V3 twins and relationships. If you do want to use the tool (which I understand), check if the V2 models are good enough for your requirements.

If you needV3 related solutions, check out if using Azure Data Explorer will work for you.

As seen in this blog post, graphs can be visualized using the (Python) support in the database.

Next to that, you can also work with the graph operators in the Kusto language.

I have not worked with this at this point but check out this documentation.

It seems it should perform well, at least better than the Python graph support, I expect.
