 > Migration notice: the project has been renamed from DataVizHub to Zyra. The new import namespace is `zyra` and new console scripts are `zyra` and `zyra-cli`. For a transition period, the legacy `datavizhub` namespace and CLI remain available and redirect to Zyra under the hood. Please begin migrating your imports and usage examples to `zyra`.
