🎉 Release v1.0.0 🎉

[jonmmease]

The VegaFusion team is happy to announce the release of VegaFusion version 1.0.0. This release is the culmination of several months of work on both VegaFusion itself and its new dependency: VlConvert. This version introduces a brand new mimetype based renderer that is compatible with many notebook and compute environments without requiring custom extensions. It also includes a new transformed_data() function that makes it possible to evaluate the data transforms associated with an Altair Chart and return the result as a pandas DataFrame.

Finally, we’re thrilled to announce that VegaFusion has been adopted by Hex and is now licensed under the same permissive BSD-3 license used by Vega, Vega-Lite, and Altair.

Great work! I'm very happy to see the alignment of the licenses. It is a big win for the Vega community!

[binste]

Indeed, thank you very much for all the hard work that went into it and for changing the license to BSD-3! Great to hear that Hex is supporting the projects further development. Looking forward to start using the new mime renderer :)

[jonmmease]

Thanks for the kind words @jcmkk3 and @binste, I hope it's useful for your work! If you try it out, I'd love to hear how it goes.
