Better late than never?
You could use the Python diagrams package instead of directly creating dot/graphviz code.
The diagrams package will use Graphviz under the hood and can generate dot output files, but it supports AWS, Azure, GCP, Kubernetes, etc.
You can even create your own Custom() types if you have the logos.
The only caveat is that the software does not support fine-grained positioning like you can do with dot format.
